We loved this place. It was very cute and the location couldn't have been better however, I think it is a little small to be listed as sleeping up to 5. We were a family of 4 - two adults and two teenagers. We were very cramped. It would've been perfect for just my husband and me with one kid - or two little ones - but with 4 grown people, it was very tight. I can't imagine it with five! The second sleeping area can't really be considered a bedroom - it is a sleeping platform with a mattress which little kids would LOVE but grown-ups won't be able to sit in a fully upright position. There was a cot disguised as an ottoman so one teenager stayed in the loft and the second on the cot.
It does have air condition but being on the top floor means it simply BAKES in the hot sun all day so it gets very warm - so much so that the air conditioner couldn't really keep up. Granted we were there during the dead heat of July so I'm sure that didn't help, but an extra fan would've been a godsend! Surprisingly tho, the loft stayed very comfortable as there was a fan provided for the area.
The bathroom was extremely tight. Not nearly enough room to hang 4 toiletry bags but again, it would be fine for a couple with a small child.
The location made up for everything! It is located right in the square and within walking distance of literally everything. I think we only took a cab once and that was to the Vatican because we woke up late and were on a schedule. The market happens daily except Sunday's I think and so there is constantly fresh fruit and other produce.
Overall, we had a great stay despite being somewhat cramped with four people. The location was wonderful and the apartment was very cute. I would stay here again with my husband for sure! I would also recommend this place to a couple with smaller children (as long as they are okay climbing stairs since it is on the top-level). It would be ideal for a young family or couple!
