Pros:
- Carla & Joel are very responsive and seem to be nice people.
- The apartment is tastefully decorated.
- There is an in-unit washer/dryer which is a great convenience.
Cons:
- The apartment is located on street level and its one window faces the street. Because of this, especially in the summer you have to choose between opening the window for fresh air or closing it to keep flies out (which were a problem for me). It also limits privacy.
- The wifi was pretty slow
- The TV is small (not an issue for me but might be for some people)
Overall for a short stay in Alfama these things may not be problems for you, but they're things to be aware of.
