This was lovely and comfortable — and very quiet! It’s also well-located, right off of the canal, across from the inner city, and in front of the Karmelitermarkt (and about a 15 minute walk from the Prater!) I hit a hot spell in Vienna, and the air conditioning was very welcome (although it got a bit warmer on the mezzanine when I went up there). There were lots of thoughtful touches, including umbrellas, a luggage scale, and lots and lots of tourist information. Another armchair might be welcome if several people stay there, but otherwise, it is well-appointed.
