We stayed at the Sir Adam hotel for 5 nights and this was one of the worst stay experiences we ever had, as detailed:||1. Terrible housekeeping services and unresponsive and inattentive staff||i. On day 2 night when I went to bed I noticed that my pyjama top was missing. I believe it was taken by the housekeeping during change of bed linen by mistake. While I report that incident to the reception the next day morning, the reception seems don’t care about it and they never update me on the progress. I had to make enquiries to the reception every day and what I got from them was "no reply and no progress", which was very frustrating. After multiple enquiries day by day, eventually it was revealed my pyjama top was taken by the housekeeping and it was found in the contract out laundry services. The reception did not send the pyjama top to me and eventually I had to got it back myself at the reception on the day of check out, not sure whether it had been washed. For this incident it appears to me that it was not their fault and I never hear a single word of apology or sorry from any one of them for the inconvenience caused.||ii. On day 2 we noticed that the complimentary drinking water had not been refilled, therefore we phone to reception for the water. After waited for more than one hour with two phone calls at the reception, still no water came and eventually I had to go down the reception and got the water myself. ||iii. On day 3 when I got back to our room I noticed that the toilet brush was found inside the toilet and the toilet had not yet cleaned. Moreover, the toilet tissue paper had not been refilled. I believe the housekeeping did not finish their work but walked away. ||As the toilet tissue paper had not been refilled, I asked the reception for the tissue paper at 3 p.m.. I had waited till 4:30 p.m. and no tissue paper, therefore made another phone call again, waited till 6:30 p.m. and still no tissue paper. Eventually I had to go down the reception again to get the tissue paper myself.||iv. At one night we came back to the hotel after midnight and found out the front door of the hotel was closed and locked. Without any instructions on the front door we had to explore around the building for the night entrance. This is a pitfall as I believe there should be some instructions at the front door about the night entrance and at least the reception should mention about it during check in. ||2. Unauthorised charge of unconsumed minibar item||Upon check out we confirmed with the reception we did not consume any minibar items. But one hour after checked out I received an email with an invoice stating that I had consumed one bottle of Heineken beer and my credit card had been charged for nine Euro without my authorisation. I reply to the hotel by email stating that we did not consume any Heineken beer. In fact all four bottles of beer were on the table above the fridge. In the reply email I had attached a photo taken upon check out showing that all four bottles of Heineken beers were in place on the table. But they just simply ignore my reply email and they did not reply and refund until I made a complaint to them two days later. Therefore please be very careful for their unauthorised charging. ||3. Missing Marriott points and night credit ||As the Sir Adam hotel is one of the Design hotel, we could earn Marriott points and night for the hotel stay. But one week after check out I still haven’t received the points and night credit. Upon enquiry they just reply me there is some technical issue but so far I still haven’t receive any points and night credit. Therefore please be cautious if you are the Marriott member in an attempt of earning points and night by staying in the Sir Adam Hotel.||As evidenced above, my unpleasant experiences were not caused by a single incident or due to the fault of just a single staff. I believe there is significant systemic deficient in the management, training, and supervision of the hotel team. As a result of poor housekeeping services, unresponsive and inattentive staff, together with the unauthorised charge of unconsumed minibar item and missing Marriott points, I believe this was the worst hotel services I have ever encountered and therefore I would suggest to think twice before you consider it.
