First off, this space is HUGE! Pictures really don't do it justice. Mattresses are all inner spring, and the one in the master bedroom has a plush top, and while I normally have back issues with spring mattresses, I did ok on this one.
Something not shown in the pictures (as far as I can recall) is that the master bathroom contains a contoured soaking tub, which is SO nice!
Full kitchen facilities, two bathrooms, a private balcony, easy access (it IS on the 4th floor, FYI, but there is an elevator and stairs) make this an absolute steal!
Attentive hosts, as well, who helped us deal with a small issue that helped so much.
