Jorge's apartment was perfect for us as a couple visiting Lisbon.
The apartment is located in the Bairro Alto district, which is very atmospheric and lively, with an enormous number of bars and restaurants on the doorstep. Across the road is a very nice viewpoint with a large kiosk bar, and next to it is the very cool Elevador da Gloria tram, allowing access down to Rossio and Restauradores areas below. The apartment is also pretty well situated to walk into the quieter and trendy Principe Real area. The closest Metro station is Rossio walking downhill, or Baixa-Chiado walking uphill (this way is more luggage friendly). From the airport it's about 45 mins on the metro and should cost no more than €2 pp.
The apartment itself is very well equipped and we found it immaculately clean. It's quite compact, with a living room / kitchen with a large TV with cable/satellite, a bedroom with good size bed and a bathroom with shower. Very comfortable and convenient.
We didn't find the street noise too bothersome but it is ever present - and not just on Fri/Sat - and those unused to sleeping in a city might take advantage of the earplugs thoughtfully provided. The kitchen was well equipped with appliances, with a few pieces of basic tableware, kitchen implements, etc. and the bathroom was well stocked with toilet paper, shampoo and shower gel. There was also a laundry room, which we didn't make use of. There is aircon in the living room and bedroom.
The apartment is up a fairly steep flight of steps inside the building, but if you are in Lisbon you should get used to going uphill anyway...
Finally, Jorge was a really considerate host. His directions to find the apartment and check-in instructions were perfect and he gave us some restaurant recommendations and checked in a couple of times via message to make sure everything was okay.
All in all, we'd highly recommend Jorge's place and would definitely consider staying here again!
