Ninas house is very lovely, clean and very good located. The hosts are tolerant and responsive. Ask them for any advice regarding restaurants and other import things You need.
Location is central, very close to public tranport and city attractions, but is not crowded, what is important for good sleep. In same time it is close to Campo San Margherita square for night parties.
The room is beautiful and cosy with all Yoo need. Maybe the bed was to soft for me, but in overall, we were very happy to spend our 3 beautiful nights in Venice at Ninas house. Thank You!
