The Moxy and Residence are in the same building. I could see at the time of booking the Moxy is an 'edgey' brand, not for someone in their 70s. Residence looked more conventional and meeting my needs. In the 'dining room' there was pounding bass music with screeching synthesised vocals (maybe what you would expect in edgey Moxy), I asked for somewhere quiet to take my dinner and was bluntly told NO we have loudspeakers throughout. The £22.95 dinner offer is a bit of a con, some starter and main course combos are less than than that. My starter came promptly but after another hour my main had not, after enduring the noise I left - they waived the charge. The toilet in the room did not flush properly. The rooms are nice and the location great for pausing a journey from Heathrow to the west via Slough/Reading stations but I will not stay there again. Indeed it has seriously tarnished my view of Marriot Bonvoy. I could hear the 'music' in my room on 5th floor up to 11pm, don't which noisy public area 4 floors above or below it came from.
