We have spent two nights at Borgo flat. The place is not huge, but enough space for 6 adults. Very clean and nice. The location is wonderful - from 10 to 15 minutes walk to the major sights, with huge amount of bars, restaurants, shops.
There is one point to be mentioned. The apartment is situated at the 4th floor in a very old traditional house, has no elevator and very curt stairs. It was fine for us, but might be a problem for other guests.
I would sincerely recommend it to my friends.
Thanks for the stay.
