I had a great stay in David's apartment. I didn't meet David but he communicated promptly by text and email. The apartment is small but fine for for one person or a couple. It is very close to the beach and restaurants which was great, but with this proximity comes a little noise in such a busy area. There is also some construction noise during the day, but this was not a concern for me because I was sightseeing for most of this time. I recommend this apartment for a visit to Copacabana.
