We really enjoyed our time at Taynara's apartment. It's best part is definitely the location. You can reach the old town by foot and the Rato metro station isn't too far either. Principe Real park is nearby where we had breakfast every morning. There's nice cafés, a mini market and restaurants very close to the place.
Everything was clean, well organized and in great condition in the apartment. The only minus of the apartment is that there is no air conditioning or ventilation (only one window and a fan). There's no window in the bathroom either so the apartment during summer is hot and humid. We mainly used the place for sleeping so it didn't bother us that much but during the night is was a bit hot.
All in all, would definitely recommend Taynara's place for everyone who wants a place from Lisbon.
