Got to the place after manager left. (after 8PM) Found my cardkey in envelope with my name and room number on it, taped to entrance door. Card allowed me to enter building but did not open my room. Another guest showed up and his card opened 'my' room, which apparently was his. There was absolutely no way to contact or talk to anybody. Went to the semi-dark lobby/reception, trying in vain to find a phone number, a posting or any other means to get some assistance. Waited for an eventual response to my emails. Gave up, and went to another hotel for the night. Got a refund. Apparently, somewhere among other things, there were also instructions to call security in case of an emergency - and I should have done that. Anyway, the place is nice, location not so convenient, but better be there before the manager leaves to avoid unpleasant surprises.
