We stayed at Pier Paolo's place for 6 nights. Apartment was very clean and very well located. It was walking distance to most of the main sites you would like to see. Coliseum was 10-15 minutes walk. Main train station Termini again about 15 minutes walk if you wanted to go on a train journey such as Florence which we did (1.5 hours away - trains are great). You can walk to all the other popular sites again easily Roman Forum, Trevi Fountains, Spanish Steps about 30-40 minute walk. If you want to take the metro Manzoni metro station is 10 minutes away. There was a local Coop supermarket 5 minutes away which has everything. Also some local mini supermarkets scattered around open till late. It has a beautiful large terrace that we thoroughly enjoyed. Lots of cafes and restaurants nearby. Check in and out was very easy. Hosts arranged us taxi pick ups to the airport and back. Again it was like clock work. No problems at all. Kitchen was tiny but practical. There were plenty of clean towels and soap, etc. Overall we had a very pleasant stay and I can happily recommend this place to any future guests.
