The apartment is great and you will find everything you need there. It is very close to Alfama, which was for us the nicest part of Lisbon.
Paulo and Joana welcomed us with a bottle of wine and some fruits. Also they provided us with some very helpful information about Lisbon and the main attractions and how you can find them from the apartment.
The apartment was very clean and well equipped with everything you need. My boyfriend and I stayed there with another friend who had her own room. It is really comfortable for three people.
We enjoyed staying there.
