Alberto's place is just excellent. Very clean, bright, decorated with taste and style. Comfortable and large beds. Very spacious flat (we stayed at 4), with lot of space to put clothes and everything. Two bathrooms present an advantage.
The area is a residential area, with a green view from the huge balcony, it is a little bit further from the city centre, but it is an advantage that it is not noisy at all. Bus stop is very near, the metro station is a little bit further. It takes cca 10-15 minutes walking to the Saint Peters Basilica. Not far from the flat, there is a really big supermarket.
Alberto answers very quickly to all questions. He gave us tips about the area, cafes, transport etc. We could even stay longer on the last day.
I would really recommend this flat to everebody who wishes to find a nice flat to stay in Rome and does not like noisy places.
