I stayed about a week at Marco's apartment. Very nice place, comfortable, not too loud at all for Lapa. About 15 min walk from the metro, nice view too. Just be careful at night, some streets in Lapa can be dodgy. All the apartment in general was well equiped, the shower could be more warm but was ok, was luck warm most of the time. Internet went down for almost 2 days but came back. I didn't meet Marco in person but communication was easy. Honestly, the only thing missing is a washing machine! I recommend it for short stays.
