We had a great stay at Jorge's place in Lisbon. The apartment was really nice and clean, with all of the amenities we needed. The internet was strong as well. Apartment building itself and neighbors are really quiet. Apartment is in a great location - just 7-10 min walk from the train, and 15-30 min walk from many sites in Lisbon. Lots of great restaurants near by. Tantura and Flor de Laranja were amazing restaurants just 5 min walk away. Many grocery stores nearby as well. Jorge is on-site during the day if you need help.
Only thing to be aware of is the street noise. There is a nightclub right below and several nearby, so you'll hear noise until 2 or 3 am every night. However, for me, it was more ambient noise at a pretty consistent volume. I'm a light sleeper, and I didn't find it too hard to sleep through. I also really appreciated that Jorge let us know beforehand and provided ear plugs and sound machines - it's never fun to be surprised by loud noises at night.
Overall, great stay and would love to return! Highly recommend.
