Flávio was exceptionally friendly and helpful, a really great host. He was very good at communicating on messages before arrival. Flat is very conveniently located, it's not in the historic centre of town but very close to the tram stop and that was not a problem - only 15 min to central station. We found it was worth saving the money by staying a bit further out, especially because Amsterdam is quite small anyway! Excellent wifi connection and the room on a separate floor to the rest of the living space so good privacy. Room faces onto a semi-private courtyard so quiet at night. Many thanks to Flávio.
