Just some problem when I checked in as there was no staff at the reception and I needed to call and ask for help. It was lucky that I got a local sim card and could make a phone call. There were two other guests at the reception who told us that they had waited for over half an hour but they could not find any help as they did not have a phone card to make local call. But it was in fact easy to check in if the staff told us in advance how we could get the key.
Also the wifi did not work at all.
