This is a fantastic apartment. There is plenty of space for 3 couples and we fitted in a couple of children too. The whole apartment is very impressive but the star of the show is the rooftop terrace; plenty of room to sit around and have a drink before going out for the evening. In warmer months I am sure it would be a great place to have breakfast too.
The location is great. Nothing in the city seems too far away. Campo de Fiore is very entertaining both day and night and all the food and drink of Trastevere is only a 10 minute walk away.
The area has a lively nightlife and so there is a little noise in the evening for the people sleeping in the main bedroom. It was never a problem for us but very light sleepers should be aware.
We were a very mixed group of ages but we all very much enjoyed both Rome in general and this apartment in particular.
