We stayed with Mario for three nights. It was very easy to get to the station from the airport by metro, as the train station (Campo 24 de Agosto) is right next to the house. Checking in is very easy and uncomplicated.
The room is bright and modern. The private bathroom is located on the opposite side of the corridor. The kitchen is fully equipped, e. g. with fridge, freezer, dishwasher, fridge, etc. We kept some drinks and fruit in the fridge.
The city centre and the river are only a few minutes' walk away. We rented bicycles for four days, which was a little bit unnecessary because everything can be reached either on foot or by metro. Nevertheless, we enjoyed a day trip by bike to the beach along the river. One trip took about 45 minutes.
We appreciated Mario's quick reactions and his helpfulness. We would stay at Mario's place again.
