This building is a modernist architectural gem! I didn't see a single similar building in all of Lisbon. It is quite spectacular. The interior of the apartment definitely has some deferred maintenance -- tiles missing from the wall in the kitchen (shown in listing photo), a wall that had been re-drywalled and seamed but not yet painted. As noted in the listing, there is no smoke detector. What is not noted in the listing is the potential fire hazard of the water heater in the kitchen; in the photos in the listing, it has a cover over it, but during my stay there was no cover and the gas flames were clearly exposed; it was kind of cringe-worthy, given the lack of smoke detectors. The cleanliness of my room was very good. The cleanliness of the common areas of the apartment was adequate, especially if the other guests were fastidious. If they're not ... well, it's not getting a daily deep clean. When Samuel cleans, which he does after a guest leaves, it is pretty good. The kitchen has everything needed (although depending on the dishwashing skills of previous guests, you may need to re-clean dishes before using them), the laundry machine works properly, stove was easy to use, with plenty of pots and pans in good shape, water was sufficiently hot for a good shower. If you are short like me, you may be taking a shower holding the shower head, because I could not reach to attach it to the holder which is pretty high up. If you are tall, you will appreciate that the showerhead is quite high up! I had a few difficulties getting into the apartment -- the lockbox has buttons on BOTH sides, which I had to have a stranger on the street show me, and then I had to ask another random stranger on the street to come up in the elevator with me to help me understand how to use the key to unlock the apartment door (you counterintuitively have to pull the knob HARD towards you while very subtly clicking the key to the right, then once it unlatches push the door in). There are two functional elevators in the building, which is nice to know. Both were fully operational during my visit. I very much enjoyed meeting Samuel and practicing his English with him. He is a genuinely nice man and wishes to help his guests feel at home without imposing on their privacy. While I was there, one guest thought she lost her keys and he was very helpful trying to get the situation resolved, and contacted me to see if I was currently in the apartment to let her inside.
