The flat provided by Matteo is a grate place to enjoy Copacabana beach. It is exactly as in the pictures (which is sometimes a problem on airbnb), also very clean. We did not meet Matteo personally but his friend Mario was also most helpful. There is a doorman and safe in the house so ideally you should not worry about ur things getting stolen. Around the flat there are a number of places to buy food and a number of restaurants. The metro is 10 minutes away. I would definitely recommend this apartment to stay at, not only becaise of the location but also because of the host.
