Paulo Eduardo was very helpful and accommodating regarding our arrival time etc.. His father who lives in the same building helped us with minor issues.
However, the apartment doesn't meet the requirements to host a group of 6 and we felt very disappointed. Except a living-room with two windows and a nice bedroom with a window, none of the three other rooms have windows, which is unacceptable. Furthermore the two bathrooms are very tiny and the toilets and showers constantly leak, so that there is always water on the floor.
We were disappointed in comparison to what was proposed on the website and would not recommend a large party to stay there.
