This place was FABULOUS! i contacted the host before hand and she got back to me almost immediately. She arranged transport from the airport for us, and also allowed early check in due to it being christmas. There is a lovely fresh food market in the square opposite the flat, as well as lots of local shops to buy anything you need.
Just be careful, as once you are out for the day, you are spoilt for choice for places to eat, so don't overbuy food to cook at home. If you do eat in, there is everything you need. The quality of the flat and it's furniture superseded expectations. It was extremely clean, beautifully decorated and in such an amazing location. We spent ages looking for a place to stay and were so please this is where we landed up. Rome is very big and Trastevere really appealed to us, with the cobbled streets, high colourful buildings, twinkling lights. We only used public transport on the way back to the airport. We walked everywhere. We felt very safe. Amazing!
