A great place to stay in Lisbon! I stayed here 2 weeks.
The location is really good. 2 min walk to the metro station and 15-20 min walk to most attractions and other neighbourhoods. Also near the apartment are a lot of nice bars, cafes and restaurants. Lidl is very close as well. There is a nice co-work space nearby (LACS).
Safety was important to me, as a solo female traveller. I always felt safe at the apartment and in the gated alley leading up to it.
The apartment itself is really neat, clean and stylish. The bed and couch are comfortable. It has 3 windows so it feels light and spacious. Although it has no heating I was never cold (mid February). There is no noise from other apartments or from traffic, which I heard is quite rare in Lisbon.
There is everything you need to cook and eat, wash the dishes and so on.
Nuno is very quick to respond and a very kind host. He acted quickly when the lock needed new batteries and showed me his recommendations on the map.
In short, this is apartment is a great choice when staying in Lisbon, also when you are staying longer. I will stay again if I’m in Lisbon.
