AVOID SWEET-INN PROPERTIES AT ALL COSTS.
The check in experience was appalling, one of my team couldn't access on the only day he needed, so I had to pay for an alternative night in a hotel. It took many hours before anyone responded even after I said there was a check-in issue. We had advised our check in time of 4pm, and we were exactly on time. No one helped us. Eventually one of my team was able to find someone in the building who had an entry code for the lock, but this was too late for one of my team.
A poorly executed attempt at a "digital key", enforcing downloading of a private app, and NO ALTERNATIVE method of access was emailed to us until it was too late. No emails with access codes to the app were ever sent despite many emails asking for support.
The phone number given for support was not in service at 4pm, nor any other time. The 24-hour whats app contact service took until the next day to respond, and we had equally slow response time via the in-app chat.
