This is the worst Airbnb that i have stayed in thus far. while the location of the apartment is great, the check in process was smooth however the kitchen and bathroom was bad. please note - i have initiated a refund request for 5 out of 10 nights, and have received 1 night refund thus far. the location of the apartment is great for London, doorman building is not easy to get in London. my wife and i enjoyed the stay here until the 5th day when the sink in the bathroom clogged up. the maintenance guy came in the evening and did a temporary fix promising to come fix it permanently the next day. on the 9th night when my wife and i returned back to the apartment around midnight the bathroom sink again clogged up and when we turned on the washing machine then even the kitchen sink clogged up. we called the porter for immediate assistance who said he couldn't do anything because Chelsea accommodation doesn't have a replacement deal with them, he also said that no one from Chelsea accommodation was picking up the phone. the issue was that our clothes were stuck in the machine at 12.30 at night and we had to leave for the airport at 8 am. and both the sinks were clogged and unusuable. we messaged the hosts and at around 1 am the porter came back saying he can provide an alternative 3 floors below our current apartment and a long walk away from the elevator. no help offered to clear the sinks nor to the leaky tiles in the bathroom. it was late, we were tired and didn't want to waste anymore time and energy, we somehow managed to finish the washing cycle around 3 am. really disappointed by the lack of service. in our view no work was done as promised on Thursday. Chelsea accommodation claims someone came and fixed it on Thursday but there is no proof shared yet. also it is shocking that someone entered the flat without our permission, this shows the lack of security and lack of professionalism to actually ask your tenant's permission to enter while they are not there. really disappointed and upset. the building is great, just dont use Chelsea accommodation. we really liked the location and the building. the doormen were friendly too.
