Karen's place was fantastic. The place was nice and modern and clean and you can't complain about the views from the 52nd floor. The condo is about a 10-15 minute walk from the main center of the city, which is a pretty pleasant walk. It's also super convenient to get to and from the airport via the SkyBus.
The price was great for our group of 5 and Karen couldn't have been more helpful in getting us sorted, making sure we had everything we needed, and even letting us check in early. Would definitely recommend!
