Leiden is a university city in the South Holland province, positioned between The Hague and Amsterdam on the main rail line. It is smaller and quieter than either, and for a certain type of expat — particularly those arriving for research, biotech, or pharma roles — it can be exactly the right size.
Leiden University, founded in 1575, is the oldest university in the Netherlands and has a consistently strong international research profile. The university and its affiliated medical centre (LUMC) together employ thousands of people and draw international academics from across the world. Johnson & Johnson, Janssen, and a range of biotech companies operate in the Bio Science Park on the edge of the city, making Leiden one of the more important life sciences locations in Europe.
The city itself has around 35 km of canals, a well-preserved historic centre, and a density of museums for its size that is disproportionately high — the result of centuries of academic wealth. It does not have the scale of amenities that Amsterdam or Utrecht offer, but for the people who choose it, the combination of manageable size, good transport links, and a strong scientific community is the draw.
Cost of Living
Leiden is slightly cheaper than Amsterdam but comparable to The Hague, and noticeably more expensive than Rotterdam or Groningen.

|---|---|
| 1-bedroom apartment (private rental) | €1,050–€1,300 |
| 2-bedroom apartment | €1,400–€1,700 |

The student market has a strong influence on rental prices in the centre. Properties within cycling distance of the Bio Science Park and LUMC are consistently in demand from international researchers and professionals.

Best Neighbourhoods for Expats
Centrum — The historic centre, with canals, the Pieterskerk, and the university buildings interspersed through residential streets. A mix of student housing and professional apartments. 1-bedroom rents average €1,100–€1,350. Good for access to everything, though parking is limited and the area is busy during term time.
Professorenwijk — The name references the academic community that has historically lived here. Elegant streets, larger properties, and a settled residential character. Popular with senior academics and professionals. 1-bedroom average €1,150–€1,400. Family homes in this area are well regarded.
Stevenshof — A larger residential neighbourhood in the south of the city, more modern in construction and noticeably more affordable. 1-bedroom average €950–€1,100. Good cycling access to the Bio Science Park. Popular with researchers and lab staff who want more space for less money.
Merenwijk — In the north of the city, close to the Vliet waterway and with reasonable access to the Bio Science Park. A calmer neighbourhood with a mix of family homes and apartments. 1-bedroom average €1,000–€1,200.
Working in Leiden
The Bio Science Park is the primary employment hub for international arrivals. Established in 1984, it now houses over 150 companies and organisations working in biotech, pharma, and medical research. Major tenants include Johnson & Johnson (Janssen), Galapagos, Leiden University’s technology transfer operations, and a range of spin-offs and scale-ups. If you are a scientist, researcher, or professional in the life sciences sector, it is one of the more active hiring locations in the Netherlands.
Leiden University Medical Centre (LUMC) is both a major teaching hospital and a research institute, employing thousands of clinical and research staff. International recruitment is standard — the research institute has active hiring across many departments.
Leiden University itself employs academic staff across all faculties. The Arts and Humanities, Social Sciences, and Law faculties have significant international hiring alongside the better-known science faculties.
Outside academia and life sciences, the employment market is more limited than in larger cities. Many Leiden residents commute to The Hague or Amsterdam — the rail journey makes this manageable.
Coworking options are more limited than in larger cities. The Leiden Bio Science Park has coworking space through the YES!Delft incubator’s Leiden node, and there are a handful of smaller shared office spaces in the centre.

Getting Registered
Registration is handled by Gemeente Leiden. Appointments at the Stadhuis can be booked online. Waiting times are typically 1–2 weeks.
The university’s International Office provides arrival support for incoming academic staff and their families, including guidance on registration. If you are arriving through Leiden University or LUMC, contact the International Office before you arrive — they can advise on the most efficient process.
Standard documentation: passport, rental contract, employment contract or proof of sufficient funds. BSN issued on registration day.
Use the BSN Planner to prepare your documents before your appointment.
Healthcare & Insurance
LUMC is the main hospital and one of the leading academic medical centres in the Netherlands with particular strengths in oncology, cardiology, and rare diseases. For general practice, English-speaking GP practices are available throughout the city, particularly in areas with high concentrations of international residents.
Finding a GP can take 2–4 weeks. The international community associated with the university and Bio Science Park means there is reasonable English-language GP capacity, but Leiden is small enough that availability is limited compared to Amsterdam or The Hague.
Health insurance is mandatory from your first day as a Dutch resident. Premiums start around €130/month with a €385 annual deductible. Use the Health Insurance Wizard to compare policies.
Transport
Leiden Centraal is on the main Amsterdam–The Hague rail line. Trains to Amsterdam run every 15 minutes and take 35 minutes; The Hague is 15 minutes. Utrecht takes around 45 minutes with a change at Alphen aan den Rijn or direct via Gouda.
Within the city, cycling is the default. The Bio Science Park is around 3 km from the city centre — an easy 15-minute cycle. Buses connect the main neighbourhoods to the station and Bio Science Park.
Schiphol Airport is approximately 20 minutes by train, making Leiden one of the better-connected smaller cities for international travel.
