The property requires two apps to enter: the latch app and another one developed by the property. The instruction and code for the latch app never arrived - even after we contacted the property. My apartment uses latch and I have no issue receiving any related info except for this property. For the other app, there was always a "cannot connect to server" error message, preventing us to do anything. We ended up booking another hotel and since this payment was not refundable we basically wasted a few hundred dollars. Communication is way faster if you let Expedia customer service contact the property for you - we told the property about the check-in issue in the morning and there was no response until we contacted Expedia.
