Everything was as described and fantastic. We were a party of 2 couples Parents, daughter and boyfriend and thoroughly enjoyed staying at the apartment. Plenty of room, very comfy beds, great views from the balconies and good amenities. Flavia made us feel very welcome with traditional "February" cake and showed us around. They had even added some room decoration in keeping with Valentine's day which we thought was a lovely idea. Took us about 30 mins to walk to Colosseum but once we used the underground we never looked back. The metro is cheap and easy to use and links well with buses so you can get to all the sites you need in Rome.
We were there for a week and ate-in some nights, also used 3 of the restaurants close to the apartment, all of which were good and not bad value at all. small supermarket near by and pharmacy.
Overall was exactly as described and a fantastic place to stay to see Rome and just have a great time. Would highly recommend our hosts and the apartment to anyone - so long as you are ok with a very small lift or walking up 10 flights of stairs ( although they are very nice stairs)
