“Great value”
+ We liked the large, clean, beautiful apartment, with whole foods in the same building for convenience. This was just what we needed for a night before a flight. Space to repack our bags, kitchen for a quick dinner and breakfast, and great value. Also, we were glad not to be annoyed too much by the trains passing by just next to the hotel. We had a worse experience in downtown Denver.
− I am not a fan of the full virtual check-in when it is more intrusive than a regular face-to-face : We were asked for information (and emails) of everyone, ID copy and face recognition for me, pay 200$ deposit in advance, need to create a sonder account and download the app to get the check-in instructions and book a parking spot. That too so long, was intrusive, and was unexpected. At the very least, we should know about this at booking on booking dot com because so much is happening outside of booking secured communication. Finally, for a longer stay and more than four people, I would worry about the lack of chairs and kitchenware.
