The person who did the check in was really pleasant and friendly, however, there wasn’t any technician to fix the heater. And therefore, we had a very cold night. The portable heater, we got from the gentleman whom did the check in, only work for a couple of hours. Also, there is a big gap underneath of the main door. Hence, a lot of cold air comes in making matters we’re. As for the rest of the unit, we have no additional suggestions. And thank you
