The apartment is in a great location and nicely decorated, but there are some things to consider:

The property is on a slope, like so many in Lisbon. That means you have to climb lots of steps – nothing for people who have a problem with it. You also have to know that this address cannot always be reached by taxi, as there are barriers that are closed at certain times. This information is important if you arrive or depart with luggage.

A welcome by the owner, as described in the other reviews, was not given. We were instructed to pick up the key at an agency office some blocks away, which unnecessarily delays the arrival.

The location is surprisingly quiet for the city center, if it weren't for the lack of impact sound insulation in the apartment above. If you are a light sleeper, you will be there live from 6 a.m.

Now we come to the biggest problem:
We were looking for an apartment that has 3 bedrooms for our stay in Lisbon.
This apartment fulfills this requirement, but one bedroom has no window and is a single room on the ground floor, directly opposite the front door. The other rooms are on the 1st floor.
Without ventilation, the room is unusable for sleeping. An open door is not an option, as the stairwell in the old building smells very clearly.
This is not stated in the description of the accommodation - otherwise we would certainly have opted for another apartment!

Availability of the agency: initially we had no wifi in the apartment. There was an immediate response and a quick solution to our request. Multiple requests never responded to the representation of the sleeping situation! The lack of a bedroom was a real problem for us.

In addition, some room doors must be reworked because they can only be closed with great effort, or not at all (bathroom door).

Another bedroom on the first floor also has no window to the outside; but you can ventilate sufficiently through the window of the bathroom and a window to the dining room.

There is no built-in heating only various electric radiators in a storage room.
