Our apartment on Sonnenfelsgasse was beautiful! The charm of the street, building (circa 1500's perhaps?) and apartment was exactly what we were looking for. As stated in the description, the apt was quiet (good sound-proofed walls), and nicely appointed. There is a full kitchen, with espresso machine, and a washing machine which was well-appreciated! An added touch of a record-player with a few classical albums, including Mozart, was lovely and we used that on one of our afternoons in the apt. There were many maps and guide books to assist us in planning, too. The location was perfect, and we were within a block or few blocks of so much. The windows, the courtyard, the street, just all of it was really lovely and we would definitely stay again. It did not have air-conditioning, and we stayed when temps were above 90 (and high heat index), but there was a fan, and at night it cooled so sleeping was not a huge issue for us. We learned that no a/c is common; do not let it detract you from staying here. Lovely place!!
