Tldr: put in the wrong room, and the room was mouldy. The staff didn't care. After waiting 10 days for a response to my complaint, I got £50ish worth of points as an apology.
Really disappointed with this one. I was very exited to visit for a relaxing weekend, and as we drove up the drive it appeared we had picked well - first impressions are great. But it turned out to be a complete let down.
When we arrived, the room wasn't ready - fine, we were early - but I could see on my Bonvoy app that we had been moved from a king room to a twin. I enquired at reception, assuming this was a mistake, but was told it was in fact an upgrade (I was told this was to "balance the rooms" mind you, just in case I had thought it was a perk).
I asked if we could be put back in to a king room as booked, but was told this wasn't possible. Not a great first impression, but I had places to be so left it.
When we got in the room that night we found a bathroom with black mold on the ceiling, a filthy carpets, a rotten window, and bedside tables with drinks rings which hadn't been wiped since the previous occupant.
My partner was too tired to faff about changing rooms that night, so I informed reception in the morning - but was really disappointed to be told just that "housekeeping would be informed". It's a little offensive to act as if this was just an undusted sideboard. I asked for an email so I could follow up and was just told to email reception.
I did end up getting an apology from the hotel by email, but it just again gave me the housekeeping line. I responded with photos of the state of the room, and after 10 days and three unanswered follow up emails, I finally got a response offering me some Marriott points in return for a spoilt weekend.
This isn't the quality I'd expect from Marriott or a supposedly luxury country hotel. Based on other rooms I can only assume they shoved me in one of the crap rooms as I was visiting on reward points. I won't make the same mistake again.
On a positive note, breakfast was nice and the F&B staff were great.
