Casa Rosanna is a lovely apartment in an old building with high ceilings and large rooms. There was someone waiting for us at our arival, even though we were quite delyed. Was great to have a lift on the first and last day to carry the suitcases. The rest of the time we used the stairs as only on the 1st floor.
The bedrooms were very spacious with comfortable beds/pillows and plenty of coat hangers in good size wardrobes. The dining area is big with a round table and good chairs; the bathroms are a reasonable size and so is the kitchen that has eveything you could need, including a dish washer and an excellent washing machine/dryer.
The place is a 10 minute walk from Termini Station and very simple to get to the flat on foot following Carlo's instructions. There is a great undercover market every morning from Monday to Saturday selling a huge variety of fruits and vegetables, cheeses, fish, meat, nuts, eggs, etc. at very good prices -worth going these. There are also four or five supermarkets in the vicinity. We found the one near the church of Santa Maria Maggiore very good.
The flat is near the Colosseum, piazza Venezia and two Metro Stations (one for each line A and B).
Carlo was a great host and he was prompt in solving some of the problems that arose. We found the fridge was not working and the next day a technician came to have a look at it and as it was dead a new one arrived the next day.
The only minus was the noise level as the flat is on a main road with quite a lot of traffic. I am a light sleeper and had to buy ear plugs to reduce the noise. Having said this, I was there with a friend and she had no problem sleeping. Ok for a short stay, but if you are staying longer (we were there 4 weeks) I would definitely have ear plugs.
