Without doubt one of the nicest places we've ever stayed. The location, with its view over St Peter's Basilica is just perfect. A & S are perfect hosts. They were there to greet us and to say goodbye, organised transfers, and replied to every communication immediately.
The apartment is extremely comfortable, has been recently modernised. The location is remarkably quiet as it sits on a small road used mainly by Vatican staff. Most of the main attractions in Rome are within 30 minutes walk, and there is a regular bus if you don't fancy the walk.
We would have no hesitation in recommending this to family and friends and would definitely stay again if we visit Rome.
