We stayed for three nights in Vanessaa tiny but well designed flat. Despite its size there is everthing you need. Even two bottles of water were in the fridge when we arrived. The location is perfect to explore Florence, as you can start directly in front of the building. The train station and the official tourist office are nearby (2 minutes). Despite the location directly in the City center, the flat is very quiet.
We enjoyed our stay there very much and fully recommend this wonderful flat.
