Our experience at bed and breakfast La Festa was very pleasant. The hotel is small and cozy with only three rooms in total. The staff and receptionist were all very welcoming and made the stay feel more personal than if you were to stay at a larger hotel.
The room we had was clean and hygienic. We even had our own kitchen where we could cook our own food, although we never cared to use it since the hotel is accompanied by a fanstasic restaurant by the same name. The hotel is located close to the city center, a fifteen minute walk will get you into the red light district.
If I ever were to go to Amsterdam again, which I probably will, I would book into La Festa in a heartbeat.
