Here’s a polished rewrite of your spa review — keeping your tone balanced but clearer and more natural:

The massage was excellent, and the receptionist was extremely attentive, which made the visit enjoyable overall. There were a few issues — the bins in the changing room were overflowing, Although mobile phones are meant to be prohibited several visitors were still using theirs. I was also disappointed to see children there when my request for our nearly 16 year old was refused.
Lovely small spa. Brilliant facilities, very new and very clean. Loved trying the red light therapy room as that was new for us. The massage was great, very relaxing.
