My stay had been very good until the last night when the night staff were quite rude to one of my family members. Upon returning to the hotel quite late, the concierge started challenging my sister about whether she was staying at the hotel, to which she replied yes and even showed her room key. They asked to see ID, which is a little bizarre. Their whole approach was just quite excessive and rude and the staff made her feel very uncomfortable. Apparently this is a "security measure", yet I was never challenged or asked for my ID when returning at night.

I overheard a couple at breakfast saying that they had experienced a few problems during their stay too.

I mentioned the fact that there had been an issue when I was checking out and the manager did reach out to me quickly, but then apparently could not be bothered to respond to my email and had someone else issue a pretty standard sounding reply.

I really wanted to like this hotel, but won't be returning.
