Hello!
Mafalda's apartment is very comfortable and cozy with beautiful view. It's very close to the city center (5-10 minutes walking).
Two weaknesses:
1. We agreed with Mafalda about early check-in, but when we arrived to Lisboa, she was not ready to accept us. It was my birthday, and we had to stay at street with our luggage for 3 hours... (but then Mafalda offered us a late check-out)
2. Be careful with washing machine - it can not always give your clothes back :) Because of it we have sleapless night.
If you want check-in in standart time and you won't use washing machine it is cool variant)
