The apartment is easy to reach via ferry which runs for free the whole night. There is also a bus going regularly. The location is rather quiet, but easy to reach from Centraal. You can reach the apartment with an elevator which is very comfortable. We didn't spend much time in the apartment, because we wanted to explore the city, but Sylvie offered right away that we can cook there and are invited to feel at home. She gave us some very good advice on restaurants. Check and check out have been really uncomplicated. We were four friends in the room and it was a great weekend.
Sywie's flat is in a great location to explore the city's center. Buses stops are just outside of the door, on the main road (a bit noisy but that is what you get if you stay close to the center). Buses are frequent and the drive to the center takes about 10min. There is also a free ferry service, about 10-15min walk away. The flat is spacious and modern. Sylvie was very easy going and a great communicator (being very communicative pre check in as well as offering her advice and help later on). It is no place for non smokers but if you don't mind that, it is no problem. ;-) All in all, we had a pleasant stay at Sylvie's.
