Had a very good 3 night stay in Marco's place. Reasonable price. Walking distance to pretty much all the big attractions (unless you hate to walk, there's a metro station nearby). Just a couple of things: this house can host 8 total people (2 double rooms upstairs, and a 4person downstairs), only 1 bathroom (upstairs), and there's a good chance you'll take a cold shower in the morning, if you can be one of the lucky ones of the eight in the apartment to use it at all. Walls are kinda thin so keep that in mind. It is kinda cramped but it's a cozy apartment and looks good enough. We enjoyed our stay here.
