Threading was ok but not as good as other places I've been that were cheaper so I don't think it was great value for money really. Also they gave me a price list afterwards and it said £8 for threading in there which was lower than the Treatwell price.
Second time to 7 day spa, the staff are lovely and the place is very clean. My only small complaint is that The rooms are a bit small and sometimes you can hear everything happening outside the room.
