Robertos place was exactly as pictured, beautiful, spacious and stylish. The terrace was just what you needed and the beds were comfortable, with portable air conditioning for the room. We stayed 4 adults- with our two friends on the pull out bed in the living room which they found comfortable enough.
Roberto was friendly and very accommodating to our requests. He was very understanding too when we were still packing and a bit late to check out in time.
The only thing I would say is that while Trastevere is the area to be in, it is also a big neighbourhood spanning over a few tram lines and the location of the apartment was at the tail end at it. This means that it is about a half hour walk/ or three short tram stops into the centre of the Trastevere bustle. However, it is 5 minute walk from the main Trastevere train station, there are
Still super markets and cafes around and totally worth it for the the space and price you get for the apartment.
Definitely would revisit and recommend it!!
