There were 5 of us - in 2 double beds and one sofa bed in the entrance hall. All adults. We were all perfectly comfortable. It is a truly grand and beautiful apartment, perfectly situated in the very heart of centro storico. Completely unique. We loved it and would highly recommend. You might want to make use of the ‘welcome box’ for €65 as there are no condiments or anything in the kitchen, but the supermarket is close by and there are cafes 1 min walk away. The lift (4 flights of stairs) and dishwasher weren’t working when we were there so worth checking about that before you go. But truly - this is one of the loveliest places we’ve stayed.
