I stayed at the apartment with my fiancée and it was just lovely. The place was warm, clean, organized and super prepared to receive us: fully furnitured, good internet connection, wirh clean towels, bed sheets and blankets etc.
The localization was perfect, next to all the main historical buildings, museums and good restaurants.
On top of it, Miri, our hostess, was super attentive to us and it helped us all the time throughout our stay.
I would defenely stay in the same place in the future.
