Hoping for some recommendations…
I’m planning a spa day with a friend in a couple of weeks, ideally we would have gone to a night to nice countryside hotel (I like the MacDonald hotels etc) but we need to squish it into 1 day because of childcare 
Has anyone been to a nice day spa/hotel spa in London (z1 or west/northwest london ideally) that they recommend? A hotel with some grounds/an outdoor pool or jacuzzi would be amazing
It seems like a lot of the hotels have all the facilities in the basement so some daylight would be nice (or if it’s an amazing spa but all inside I’m still interested to know)
