I have travelled extensively around the world for work for the past 30 years and I have never before felt compelled to write such a review. I have used both Airbnb and Booking.com in the past and due to the current pandemic was happy to recommend to my son and his friends that they should opt for self-catering rather than a hotel. They found what they thought (from the photos) a nice centrally located apartment. On arrival the found that the apartment was actually lower ground floor (not advertised as such) which in itself would not have been an issue but the fact that the flat was dirty (hairs on the floor, in the bedding and shower), soiled Ben linen and a rotten tomato and chicken bone on the kitchen floor made it completely unfit for purpose and certainly in breach of the contract they had entered into with Booking.com. The property was “managed” by Hello Guest who would not respond to numerous calls. My sister based in London managed to speak to a representative from Hello Guest (Veronica) who requested that we sent an email. This was done and the implication was that a cleaner would be sent to rectify the matter. However nobody turned up (they waited from 1 pm - 9 pm approx) despite trying to contact again, Hello Guest’s representative did not reply or send a cleaner and they were therefore obliged to book a nearby hotel that I had used on previous visits to London. When Hello Guest finally did respond they offered a 50% on the cleaning charge - ludicrous particularly as no cleaner appeared for some 8 hours. I would strongly recommend NOT using HelloGuest for any booking! Simply abominable
