Margherita's flat is great.
The location cannot be better. Very close to the centre and Trastevere and in the heart of the great, calm and encharming neighbourhood of Testaccio. Plenty of local restaurants, bars, cafes.
You can use the local transport to move around or walk, as I prefer, as it is close enough.
Margherita is a very nice host that will respond quick to any emergency and she is always ready to help.
The flat has everything you will need. It is spacious and very bright. It is great to come back to the flat and enjoy the view from the terrace.
A great place to stay in Rome.
