We got the full apartment for ourselves as we were six friends. I could not meet David because I arrived a day later, however my friends did and they said he is a warm, friendly and helpful host, who even joined them for a drink. The apartment location is absolutely amazing, very close to the Mirador de Santa Catarina which is one the best viewpoints of Lisboa. The apartment is quite good equipped, fresh and quiet. The only critic (it was not a big issue) is that two of the beds (2/6) were air matresses and one of them did not keep the air for the whole night, which was a bit inconvenient.
