It's a very nice place to stay, very clean and with an amazing location. The center of Lisbon is just 20 min away by waking (with the train even less). There are supermarkets, bus stops, restaurants and attractions near by.
The kitchen was always clean and had a lot of spices & utensils.
There have been two bathrooms which were also very clean.
Our room was amazing, we had a lot of space and a wonderful view over Lisbon, we could even see the water!
If I'm ever in Lisbon again, I would go there again :)
