My partner and I stayed here for 3 nights. Marja was great and communicated with us really well. She was flexible about check in which really helped, as our flight was delayed!
Marja's place is literally just a few minutes walk from the bus stop where you are dropped off by the Airport connection bus (Leidseplein stop). It's also close to a huge variety of bars and restaurants so you're never stuck for somewhere to eat/drink.
The first night (a saturday) was quite noisy, but we expected this and we didn't mind at all. The other two nights were very quiet though!
The apartment was very cosy and clean. Marja had even left us drinks (wine, beer, water and soft drinks) and some crisps which was a really lovely touch and much appreciated.
Public transport is very close and you can reach pretty much anywhere in the city by various trams and buses at stops nearby.
Overall a fantastic stay in a brilliant, central location!
