The apartment is really cozy, perfect for a short stay in Lisbon. It is in the traditional neighborhood of Alfama, with a lot of nice restaurants and bars nearby. It is a residential area, therefore there is hardly noise at night.
Everything in the apartment was nice. Decoration, comfortable bed, nice bathroom. Also Jorge was very helpful and if you don't know Lisbon he will be able to give you some tips.

The apartment is located on the 4th floor and this was a problem for us, as we had three heavy suitcases and there is no elevator. Of course, we managed, but just be aware of it. Also, we were in Lisbon during some really warm days and nights, and the apartment doesn't have AC, so it got really warm in the apartment.
However the main issue was actually the renovation ongoing in the building in the backyard. Noise starts at 8:00 am and can go on until 19:00. They seem to be almost done, but if you like to sleep late in the morning or rest during the day, it might be complicated.
