The the building is located in a very central location (Bica) 10 minutes walking from Bairro Alto, in a lateral street very close to Bica funicular. The house is a typical Portuguese, a bit rustic but I personally think that it is what makes it very nice.
The street is quiet and Ricardo and Patricia have been really nice and discrete. My flight was delayed 4 hours and had to check in at 22:30; Patricia and Ricardo were very helpful with this. Much appreciated
