We enjoyed staying here - we were a family of four plus an extra adult - 4 bedrooms was good for the children as they didn't have to share. Alberto kindly let us check in early as we arrived before 6 pm.
The area has good transport - there are several bus stops within a few minutes' walk for lines which can take you into the city, to the airport, to the UN and the botanical gardens amongst others.
There is a supermarket and a couple of restaurants close by in case you don't want to wander too far to eat. There are also a couple of tabacs where you can buy bus tickets.
The living room is quite cosy for more than four people but it's not really a problem unless you intend to spend a lot of time there - we ate in a couple of times and there is room to get 5 people round the table.
