The initial communication was excellent, easy registration/payment and clear instructions for accessing the unit. Unfortunately, several issues during the stay led to this review.When we arrived, the thermostat was set to 65 degrees, the unit was extremely cold, and the thermostat was not functioning. I immediately sent the host a photo of the error message. For the next five days, despite repeated messages, I received responses that appeared to be automated. On day 5 of our 7-day stay, I finally received a link explaining how to operate the thermostat, but the AC issue was never resolved during our stay as it was inoperable.The property was also advertised with a beautiful rooftop deck. At check-in, we were told the key fob needed for access was located on the console in the unit. It was not there. I repeatedly notified the host, but despite assurances that it would be delivered or provided through the front desk/maintenance team, we never received access. There was no onsite staff or front desk available to assist.The final and most serious issue occurred on day 5 when the front door lock malfunctioned and we became trapped inside the unit on the 6th floor. After contacting the host, someone had to literally saw through the lock to get us out.While the location was great, the lack of personal, onsite support, unresolved AC issue, no rooftop access, and unsafe lock situation made this a very disappointing stay.
