This is a great stay for two people. Anymore than that it would be a squeeze. You can't beat the location at all, next to all the major sights and sounds.
The house is located in a great Italian square full of life. There is a small cafe/bar next to it called Uncafe that dosnt close till 2 am. This was our local, cheap and fun. However the noise can keep you up defending on how many people have spilled into the street.
The kitchen is well equipped, and is decorated lovely. The one thing is that the house was divided into two airbnbs. They are both seperate, free standing and private, but share a common hall. The people in the other BnB where loud and you could hear there conversations or when they entered and left.
Apart from the noise this is a must stay, if you have the chance to book here, do it!
