We have enjoyed staying at this apartment. The location is perfect, on the world's famous Copacabana Beach, and walking distance to the Ipanema Beach. There are lots of amenities on the beach side of the apartment as well as the back side of it. 3 minutes walk to the nearest metro station.
Philip is a very nice host. He was in UK when we stayed there. Despite the time difference, Philip responded to my messages instantaneously, or no more than a sleep away. Luzia the local housekeeper was also very helpful and cleaned the house thoroughly before we moved in.
The two aircons were quiet and very efficient, keeping the apartment cool in the hot days. The blackout curtains and double glazed windows kept the light and noises out. We had the best sleeps in this apartment during this 4-week holiday in South America.
The only problem we had was with the water heater, but Philip and Luzia got it fixed the next day. It's at the top floor of an old building, and so the shower is not the strongest, but sufficient for the summer season.
