I think this is an excellent spa for what it is...but you need to understand what you are getting into.
This is not a mega-spa, with big soaking areas and lounge areas and whatnot. You walk into a small reception area, get checked in and hang out a bit, and are then taken to your treatment room. This is a pretty large and luxurious room, you have a place to sit and a shower and your treatment area, but that's it. There are maybe a half dozen, or eight, I'm not sure. But this is not the place for a big group of friends, or to spend a day. It's just not that kind of place.
But it is a place for high-class treatments from nice people. There were four of us (two couples) so we had a broad range of experiences with different treatments and massages and we all came out very happy. I guess we had six people work with us and all of us thought the attendants were talented and very pleasant. So if that is what you are looking for--it was what we were looking for--you should be very satisfied.
Think of Jurlique as a place to spend an hour or 2 on a lazy afternoon, then get a drink outside someplace and head to dinner, and you will be happy. Think you are going to show up and 8am and be poured into your limo home at 5pm and you are probably going to be disappointed.
