John's apartment is in a great location in Copacabana with an excellent view of the beach. The unit is older, probably from the 1950s, and has not been remodeled. The kitchen and bathroom are very small, but adequate if you do not plan on spending a lot of time in the apartment.
The one drawback of the apartment is the wifi, which is shared with at least one other unit in the building. Download speeds are very slow and streaming video is not possible. An apartment in this location with such an amazing view should really have a dedicated wifi router. I'm sure guests would be willing to pay a few extra dollars for this added convenience.
