The pictures don't lie: it is a tiny space. But the thing with this apartment is the view. IT'S ALL ABOUT THE VIEW! Ok, you can't see the Tower seated on the couch, but IT'S NOT as some people said - you don't need to do a huge maneuver to see it, you just have to look outside the window. And it's totally worth it. During the day or by night it's fantastic, and to be able to enjoy the night light show from the window was a big plus.
About the lift: thank God there's one, but, yes, it's REALLY small - the tiniest I ever seen - but enough to send our luggages up/down and to use it to arrive and leave the apartment. Low point: it's only to the 6th floor and you have to carry your things to the 7th.
We basically used the apartment only to sleep and take a shower for one night; the self check in was really easy and was overall a good experience. Recommended!
