This is a great place!
1) Great host - Pietro - very polite, caring and helpful. Pietro met us at Vaporetto station late at night, which was very nice.
2) Great location - just 2 minutes walk from the nearest Vaporetto station San Samuele, and a little bit more from San Angelo station, just 2-3 minutes from Accademia bridge.
3) Great apartment - interior full of antique stuff (glass, silver, porcelain, furniture), just like a little museum of arts and crafts! Kitchen is nice, you can find almost everything that you need. Basics were available - sugar, salt, coffee, oil, etc. One bedroom offers great wooden furniture, another one - very nice view from the windows. You can also use shared terrace on the 5th floor, we never met anyone there during our 10 days stay, so it was just like a private terrace.
Overall - we had great experience, hosts and apartment are amazing, we definitely ready to recommend it, especially is you travel with senior people like my parents (apartment is on the first floor).
