Luis' apartment was incredible. It was a great design and extremely comfortable. It was also a great set-up to work remotely for a bit as we didn't have any wifi issues. You can tell a lot of effort was put into the design of the apartment itself -- very comfortable bed, a big kitchen table to work or eat, huge closets and an amazing shower.
It's located in the perfect part of town--about 5-15 min walk to some of the best restaurants, bars, cafes in Lisbon. It was also extremely quiet at night, which is a hard balance to find in such a good location.
Luis himself was extremely communicative and helpful during our stay as well--he's also extremely knowledgeable about the area so check out his guide book as well.
Overall, it was a fantastic stay and when I return to Lisbon, I'll be checking availability on this place first :)
