My stay was great! The place is so well distributed you don’t realize you’re in such a narrow building. Staying there was another experience in the city on its own.
The hosts are extremely helpful and provide valuable suggestions for activities in Lisboa and, particularly around the neighborhood.
At night the surrounding streets may seem a bit lonely (even shady if you are not familiarized or arrive at night), but I inquired and learned it was pretty safe.
There are many helpful things (mini markets, restaurants, bars) within walking distance, and quite a few bus stations that will take you to the main attractions (214 was my favorite as it had a very good frequency and quick arrival times to Praça da Figueira, which will take you to Rossio, both metro and train station).
Recommended stay!
