Nice place to stay in Lisbon!
Located just near the castle, panoramic view, near the 28 tram stop and in foot availability to key places. The only thing you need to know - if you have heavy luggage it might be difficult to get by foot from metro station as you need to climb the hill but it's very very fine for walks.
The appartment itself is comfortable for staying, all essentials are there. It's on the ground floor so you can be confused with people walking just nearby your window and if so - you can easily close the shutters
Ruben was very nice all the way! Great host!
