First of all, Tiago, our host was amazing. From the moment I checked in, he helped me with moving heavy carriers and providing many useful tips (must see place, transit, good restaurants, etc). He followed-up daily to make sure my stay was well.
His place was very clean that I didn't even have to wear indoor shoes. The beds were comfortable. What I liked the most about this place was the washroom which was extremely clean. It seems like it was newly renovated. Despite of locating in a busy area, the place was quiet with windows closed.
The place was close to many must-see/go places (mostly within 5-10 min walking distance) with many good restaurants around.
When I go back to Lisbon, I will definitely stay at this place again.
