We spent to nights in Henrique's place at the beginning of July. The place is conveniently located in one the most central and lively areas of Lisbon, and although it cannot be directly accessed with private car, it is just two blocks away (uphill) from tram station and public parking. Metro station is located at about 10 minutes walking (uphill again, it's Lisbon).
Barrio Alto gets pretty noisy at night, especially during the weekends. Earplugs are very much suggested if you have light sleep and going to bed before 4am.
As advised, the apartment is located at the third floor and no elevator is present. Stairs are quite steep so, light travelers would definitely be paid back when staying here.
Although an historical building, the apartment is recently renovated and it has a very positive vibe. Furnishing and the design are well cured. Many tips and suggestions were provided upon our arrival and we definitely appreciated them.
We definitely recommend this place!
