The description of the place is pretty accurate. The apartament is clean, bright, the kitchen is fully equipped. Close to tram/bus stop (e.g. famous tram 28 which takes you directly to city center). There's a big grocery store down the street and small cafeteria nearby. The apartament is on the 4th floor - might be a problem for people with limited mobility, but otherwise shouldn't be a problem at all (you do a lot of climbing while visiting Lisbon anyway:P). Special thanks to Paulo, who is inviting guests at the apartament in the name of Sofia, since he's a really caring, responsive and cheerful guy:)
PS. there is construction site on the next property - they can make some slight noise but only during day hour (even then it wasn't that much of a bother)
