Pros:
Good location—small shops everywhere (fish market, fruit shops, butchers, cafes, restaurants, bakeries, cloth shops, many more); you can go to everywhere in Lisbon by bus, trolly or train and bus stops/trolley stops/train stops are 3-4 minutes away; it gets quiet early at night; Pedro, the host, is very kind and responsive.
Cons:
It is away from city center; the apartment building is (I think) old—noise or odors are difficult to control; shower water gets burning hot and cold every minute; The word “rooftop” is misnomer because Pedro’s unit is not on the rooftop but it has access to the roof where one can not bring tables or chairs to enjoy it, just stand and look out.
