The hosts were very responsive, and allowed my daughter to drop her bags off before the official check-in time, for which we were most appreciative.
There are many good things about this apartment: the location (near 2 metro stops, a local market and the Natural History Museum/Zoo); it has all the essentials (well furnished kitchenette, tiny bathroom/shower with all essentials, though only one person can fit at a time); a double bed and a reasonably comfortable sofa bed; big windows and natural light/sunshine. And there was an unexpected luxury: a towel warmer. But as the hosts state, it is only 22 m2 or 237 square feet - smaller than many hotel rooms. With the sofa bed open and with one suitcase each opened on the floor, the dining table had to be squeezed into a corner, and there was little space to move around in.
Also, note that while not listed in the house rules, the hosts ask you to strip the bed sheets and take the trash to the ground floor bins before you leave, even with an $89 cleaning fee.
I would recommend this place for a single person, or a couple who share the double bed. But it is definitely cramped if the sofa bed is open.
