My friend and I went to Lisbon for 4 nights and it was amazing. The neighborhood is great! It is in between the locals with great coffee and dinner places and within 10 minutes walking you are in the city center. It can get really crowded in the city so this place is an amazing quiet house to have some rest. The bathroom is indeed small but everything works and is available. A great stay for a couple!
Also there are enough transportation options near the house like tram, metro and train.
The cousin of Alexandre, Rodrigo, helped us check in and responded very quickly during our stay.
If you want to find a nice dinner place, go to the restaurant above the market just around the corner, Santa Clara dos Cogumelos. You'll be surprised and satisfied.
