We had a very nice time in Rome thanks to Elena's hospitality. She is a friendly host, always stays in touch and we've received some useful advices about area nearby.
The appartment is nice, clean, looks like at the picture. The best part is a terrace, we like to spend time there after busy days. The stairs leading to the appartment were steep and narrow- not very convenient if you are traveling with heavy suitcases, but it wasn't a problem for us.
The location of the flat is brilliant- in the middle of beautiful, vibrant Trastevere, but just a few steps away the bridge across the river. You can reach Campo di Fiori in less than 10 minutes, Piazza Navona in 15 minutes, Colosseum in 20 minutes walking. We almost didn't use public transport - all you need is nearby. In the evening the area becomes alive- streets are full of people, music, dancing and so on. We liked it very much, it was a lot of fan. But if you prefer to go to bed before midnight, you should keep the window shut ( windows are good by the way).
So, flat is really nice, Trastevere is superb, I hope we'll come back one day.
