This is my second time staying here. Last time I stayed I wrote a great review and the surprising thing is it's even BETTER the second time. There have been some improvements made (namely the entire apartment is air conditioned now) and a water purifier has also been installed. I notice that a lot of the earlier reviews made note of the lack of air-con, so I'll stress it again. The WHOLE apartment is now air-con.
Check-in is a complete breeze. I arrived late in the evening and was in the room within a couple minutes of getting out of the taxi. The place has obviously been set up solely for airbnb guests (meaning there is no clutter or that feeling you're in someone else's house).
The bedroom is bright and sunny and has a fascinating view from the 12th floor out to the neighboring buildings. The inner lounge area is a little dark as there is no natural lighting (but personally that is something I prefer as it makes it easier to sleep-in). The place was incredibly clean both times I stayed and the bathroom/water was always hot and high pressure. Wifi worked brilliantly and my friend (who stayed at a different apartment) spent most of the time here since his own wifi was a complete mess.
The location is only about a 2 minute walk from Copacabana beach, there is a grocers next door and the entire building is locked with a doorman so it's incredibly safe. I will be staying here again next time I'm in town for sure.
