The apartment is really central, to Barrio Alto (where a lot of bars and restaurants are) about 15min by foot. There is also a metro station really close (but in Lissabon I thought it was nicer to walk). The apartment is really beautiful, high ceilings, wooden floors, and a new kitchen. The bathrooms get cleaned everyday, at least when I was there it was like that. There is one room for all the guests with two balconies. The neighbourhood felt very safe. Pedro is a friendly guy who will give you advice if you need to know where to eat or go :)
would recommend it! Lissabon is so beautiful!
