The location of the apartment is lovely: in a very easily reachable part of Alfama (5 mins by the closest metro and really close to the seaside) and also a very pretty one. Susana seems nice and gave us some nice recommendations.
Regarding the apartment itself: it is pretty basic but has everything you need. It is pretty small for a two bedroom apartment. The bathroom was also small. There is very little sunlight inside unfortunately. The bathroom was not super cleaned: we found some hair on the floor and in the cupboard under the sink. But other than that, the rest was fine.
So for me the very good thing about this apartment is the location; otherwise the apartment is simply ok.
