Stefano and Patricia are very nice hosts, respectful, helpful and available. The apartment is very clean, the bedroom is very nice and well furnished.
The location is practical because close to a metro stop and tram stop. The apartment is located in a street down the castle, between Mouraria and Graça.
There are some streets better to avoid, especially at night when you can feel unsecure if you are alone. Just ask Stefano for good advice.
Otherwise, it is a nice place to stay, with restaurants around.
