Interesting concept
A real experience. I had just won this hotel on a travel website, but had good idea it was this property before I booked. I really wanted to just try it from curiosity. Would have loved to have a place like this years ago, but maybe getting a little older and this place maybe a little too hip. 
That said, as I was staying at another property the night before and the Yotel was near the diner I chose for breakfast, I stopped in and asked about early check-in....It was 7 am, Well, if they have a room, they check you in.... or help you to use the kiosk I should say. This really impressed me as I was on just a quick weekend over from Europe for just 2 nights. 
The sunday brunch would have been great if I was not traveling alone. The whole hotel is an excellent concept. 
The little kitchen area on each floor is nice, but it did lead to one maybe un-intended trait, young guests congregated on my floor outside the kitchen and were sitting all around on the floor of the hall and it did not really look "nice" and I would not want them right outside my door. 
The upper lobby was really a part of the night club late and as I had a key issue and had to wait over 10 minutes to get attention and then had clerk on phone the next day for 5 minutes while I waited, was not overly thrilled with the service, but that is sort of the idea. It is kind of a self service concept and very good for what it is. 
A very social atmosghere.
