Diego's place is a modern, stylish apartment a little south of the main part of Trastevere. It had any amenity you would want, an extremely comfortable bed, lots of storage space and light, and it was very secure. Portable Wifi also was a great help when out and data roaming on phones was causing problems.
The location is very easy to get to if you're coming from Fiumicino airpot as you're able to take the train direct to a stop nearby and then it's only 8-10 mins walk to the apartment. It's a little bit further out of central Trastevere than we realised but if you're able to walk it takes about 20-30 mins to get to central Trastevere and for anything else the metro is extremely close.
I would have no hesitation in staying here again.
