Indeed a very nice apartment in a great location.
We stayed there over New Years Eve and we just had a few minutes to walk to the party at Copacabana beach - and back after the celebration. The apartment has anything you need for two persons. The kitchen is maybe a bit small, but with all the bars and restaurants around, we didn’t use it except for the morning coffee and heating take away food.
Alex is very friendly, quick and helpful in response, and also proactively asking if we need something.
Overall, we had a great stay in Alex’ apartment.
