Marianos flat is in a quiet compound, its possible to leave the balcony door open at night for sleeping in the big room. Bed is good for two adults. Great view from the balcony, nice to sit there. Mariano is very respectful and makes one feel at home, at the same time he gives enough space so one feels relaxed. We were there as a couple, but I would also go there alone, because I felt very much at ease. The neighborhood has restaurants, food stores..and the u bahn is nearby. What more do you need? We had a great time in Vienna, thanks also to his place and hospitality.
