We stayed at the apartment in October 22 as two couples and it is ideal for that purpose having two bedrooms and two bathrooms.
It is located in a great part of Lisbon, close to a metro station and to the commercial district. There are numerous bars and restaurants in easy (flat) walking as well as a supermarket across the road and a bakery around the corner.
The neighbourhood is lively but the windows and shutters do a great job of keeping out the noise - it didn't affect our sleep.
The apartment has been furnished really nicely and has comfortable beds, powerful showers as well as the usual kitchen amenities including coffee maker and pods.
All four of us thought it a fantastic place to stay and would fully recommend it to anyone visiting Lisbon - we would certainly stay there again.
