We were four adults, parents, adult daughter and her husband and the apartment accommodated us more than adequately. The bedrooms were quite roomy and separate and the use of blinds in place of doors posed no problem whatsoever.
The lounge/dining area was particularly spacious and the seating was very comfortable. The extra space to the side of the kitchen with table, stools and computer bench was a bonus.
Trastevere is a great area to stay in Rome and Bruno and Francesca's apartment is perfectly placed to take full advantage or it. Although the entrance is off a main street the apartment itself is totally quiet and peaceful. While it is on the fourth floor,the lift makes access quick and simple.
Contact with Bruno was always straightforward and his responses were always understanding and helpful
In short, we had a wonderful time in Rome and in Bruno and Francesca's place and I would thoroughly recommend it.
