I loved the apartment!
I was in the apartment with a close friend of mine for one week & we liked everything about it. It is located super close to the sea, about a 3 min walk. Right by the sea is also a bus station and the tram station is 5 min away. You can also walk from the apartment to the city centre in about 10 min and have a lot of restaurants near by.
The apartment has the perfect size for two people and everything was clean. It is located in a quiet street so there is no problem with loud noises at night.
Daniela, the host, is super kind and gave us a long list with tipps and recomendations for Lisbon. She answered every question we had very fast and made our time in Lisbon even better.
