We spent 2 nights at Federico Diego appartment and honestly we didn't quite like it.

Firstly, the pics of the flat are far better that the flat itself. The flat feels cheapy and muddy. There were no soap or shower gel in the bathroom on our arrival. The kitchen is very unpleasant to use. Again, it is muddy and it is not fully equiped (the kettle is too old and it takes 10 minutes and some scum to boil; there is no pan lid; etc.).

The best part of the flat is the bedroom. It is really nice and comfy. I should also mention that the rooftop must be a nice spot during the summer.

Secondly, the area also feels unpleasant and muddy. Even though, it is 15 minutes from the metro station and 25 minutes from Colosseum it looks a bit hostile and muddy.

I would still thank the host for the opportunity to stay in Rome, but I would not come back at his flat. No offence.
