The apartment is located directly in the Coastline of Copacabana with a spectacular view from almost all rooms. It has a lot of space and can receive big groups like our group of 8 people. Having more then 10 people in the apartment I would consider as difficult though due to the fact that there is only one really comfortable shower. Then there is one additional one that is still ok. The other two bathrooms only are toilets. The shower options in that 2 toilets is not really usable and should not be promoted as such.
The furniture and the beds are ok but could use some renewal. Especially a new comfortable sofa in the central living would make a big difference.
We enjoyed the stay a lot. Copacabana alsways in sight also Ipanama beach is reachable within minutes. There is a bike rental station just 30m from the appartment that gives you additional flexibility to move around. Communication with the hosts was easy and precise. 24hs security at the entrance is also a plus. With a big group I would be happy to come back.
