The flat itself is beautiful, the views of London are stunning. However, our check-in experience ruined the entire weekend for us. I was told to collect the keys from concierge by stating my name. Even though I did this, the man refused to give them to us because the previous guests had told him upon checking out and dropping off the keys, that the flat was an AirBnB. According to him, this (subletting) is against the building policy hence why he put the keys into the mailbox and reported the situation to the site manager that morning, and consequently refused us access when we tried to check-in at 4pm. I informed the host who at first accused me for stating to concierge that we were an AirBnB booking (which I didn’t), and then said she’d call concierge to resolve the situation (as she was out of the country) as what they were doing was not allowed. She could not resolve the situation with concierge, and instead, together with the help of her co-host, organised for someone to drop us off the keys. We had to wait for 2.5 hours (they arrived at 6:35pm), and were told 3 times that the person with they key would be 5 minutes when we followed up when in actual fact it was 40 minutes, 25 minutes, and 10 minutes respectively. Before checking in, we were told we had 1 free parking space in the car park and could pay for additional parking spaces - this would have to be sorted with concierge. Instead, we were sent to another concierge who refused us access to the car park as we were not residents, and we had to pay for parking spaces on the road. We asked for reassurance from the host, co-host and AirBnB that we’d have no issue over the weekend with concierge given what they’d previously said, and whilst they didn’t say anything to us, we were stared at intimidatingly when we walked past us - we didn’t feel welcome or comfortable. It was a bit unnerving given we were 6 girls, one of whom is pregnant. Whilst the host and co-host were very responsive when this all happened, and were able to send a friend to the flat the same evening to let us in, I would encourage them to organise a better check-in process for future guests and ensure concierge do not make their guests feel unwelcome.
