I have stayed here before and will probably only ever stay here in the future when visiting Amsterdam! The staff are brilliant and the rooms are always clean with all of the essentials you need during your stay. The breakfast included also has a lovely choice. The only thing I would mention is that I usually visit in winter time so have never had an issue with the heat here before, the size of the place makes it quite cosy but this time as visited in July/August due to the rooms being only teeny it was very hot and stuffy, with a couple of you in the room it was like being in a sauna and a struggle to sleep and keep cool. Apart from that, I always do and will recommend Hotel Nadia to friends.
