The apartment is amazing, mainly because of the location. The view from the living room is unbeatable with its position over the Lagoa, and with Christ the Redeemer on the far right. Its a 10 minute walk down into Copacobana which has a beach, shops, bars, restaurants and public transport, and is really safe, although there is a big hill is between! The apartment is full of quirky art and sculptures, clearly designed with someone with good taste. 3 toilets and a washing machine was really useful too. It is a little worn in places, but that just added to the charm for me. It can be a little noisy, so bring ear plugs if you are a light sleeper, but don't let that put you off. Marcelo also let us in at 8 am, which after an overnight flight was massively appreciated.
I highly recommend staying here!
