Apartment is realy cute and has everything it needs for a short stay.
Its in the middle of the barrio gotico where it gets loud and crowded during night. But after 2am everything closes and you will have a calm night. Generally the district itself is not the nicest and cleanest one in lisbon.
Joao was really frienldy and gave us some great tips. Sometimes it was a bit hard to reach him. But in the end everything went very well :)
