Caroline's place in Vienna was superb. While I never dealt directly with Caroline, her associate Paul coordinated everything and was incredibly responsive and helpful. He was able to meet us quite early for checkin and provided us a thorough walk through of the flat. The apartment had superb amenities (Wi Fi, lots of towels, and shampoo) as well as some pleasant surprises with heated floors in the bathroom and an extremely large kitchen. Paul also provided numerous maps and tour options in case we needed it. The apartment was located perfectly by Belvedere Palace and close to the Inner Stadt (5-7 minute walk). It was able to sleep me, my wife, toddler daughter and parents with more than enough room to not feel cramped. I would highly recommend Caroline's place to anyone staying in Vienna.
