Mario's place is perfect for relaxation after traveling, away from the hustle and bustle of the city. There are all kinds of stores around his place, such as Starbucks and markets, and the subway station is also within walking distance, which makes it really convenient for travelers.
Mario is a great host, nice and generous. He is the first host I have ever met who would spend some time showing me around his place, making it more comfortable to live and use things in his apartment. Mario is also very helpful, and please feel free to ask him for help if you need anything, like some quarters you need to do the laundry :)
