My boyfriend and I had a comfortable stay at Mario's apartment. Mario welcomed us to a basket full of breakfast foods and a fridge stocked with juice and eggs. We did not end up cooking, but the effort was much appreciated. Having air conditioning and Internet access was also a huge plus. Mario's home is easily accessible by the Metro, but the Metro is not so reliable (there are only two lines and the train stops are somewhat far from some sites). For a short stay, I would probably stay somewhere more central next time, but for an extended stay in a home-like environment full of interesting objects and art, I would definitely recommend Mario's!
