We really enjoyed our stay in Lisbon. Emanuela's place is perfectly located (5-10 min from the metro station). It is quite small but for a couple it is a perfectly cozy place to stay. Due to the building the walls our very thick and the humidity is quite high in the room but they put a dehumidifier in the room so it is not so annoying. If somebody prefers 100% silent, I would not recommend Alfama to stay because you can hear the steps on the street and if somebody is walking on the floors.
The room was perfectly clean and the portable wifi was very good during the sightseeing. We are super happy that we stayed in this flat :)
