This is a lovely place. as beautiful as it looks. And Nuno's communication was great. The apartment is on a high walk-up, so definitely you should know that. Also it is above Alface Hall, which is one of the biggest parties in the neighborhood, so it is super crowded on the street, and a huge party till 4:30 AM. even on the top floor, this was a bit loud. I feel like that should be in the listing.
When we were there the front door to the building was broken. completely open to the street and not lockable. Nuno seemed surprised by this and said he was going to get in touch with the building management to get it fixed, but several days later when I was back in the city and walked past by coincidence, it was still broken. The apartment didn't seem insecure since it was on such a high floor, but it was a disconcerting way to enter the building for sure.
