I spent a total of 10 weeks living with Mario in the smaller suite. Everything was fine and clean. The empregada came twice a week, changed towels and linen and cleaned the space thoroughly. Great and reliable WiFi significantly above Brazilian standard!
I loved the location, one block of Copacabana beach, near restaurants, pharmacies, supermarkets and everything you need for your daily life. Plenty of buses in front of the house and the metro station Cantagalo in walking distance. I would strongly recommend staying with him anytime.
Although Mario was actually away in Germany a couple of weeks during my long-term stay, I must point out that everything worked really well. Mario was readily available and reachable for every question or for little problems day and night and always responded within hours, often with the problem already solved. It was almost as if he was just round the corner. Mario was an excellent host, very attentive and with great answers to every question.
Thanks for all, Mario! Your location will be first choice for my next stay in Rio.
