We had an awful experience with Welkeys. We arrived to an apartment that wasn't ready, the host told us to come back three hours later and let ourselves in. We let ourselves into an unclean apartment that was an absolute mess. There were towels everywhere, an unmade bed, dirty mugs, food boxes left out from their dinner - it was unliveable! We kept trying to get the apartment sorted, calling multiple people who didn't seem to know what they were doing, constantly getting voicemails and being passed around. They would say a cleaner was on the way but an hour would pass and no one would arrive. We didn't know if to book a hotel and were given no confidence in Welkeys to fix the situation. It was extremely stressful. They were unhelpful and unfriendly. 5 hours later the apartment was cleaned in a rush job, it was just about acceptable and we were refunded for one night's stay which after the stress caused, we don't really feel was enough. Wouldn't recommend.
