Mario's is a very nice host. We were late for our scheduled time to check in and no one was at the apartment. Mario drove down immediately to send us the key, and walked us through in very details about the apartment. The place is 15 minutes walk from Line 1 subway station, so it is very convenient to visit all the museums or take trains. There are many local restaurants and bars close to the place as well. The apartment is as shown in the pictures. Since it is the winter, we did not get the chance to use the balcony, but the place itself is spacious and simply but nicely decorated, reflecting the owner's taste. I would highly recommend staying there.
