Responsive host, unique place, great location! Definitely a fun place to be! For me, there are a few quirks to be aware of before booking.
1. Only one chair isn't kid-sized if you use the couch as a bed.
2. Most of the downstairs ceiling has a fairly low clearance. Especially tall people may feel uncomfortable. As mentioned in other reviews, the lofts upstairs have a lower clearance.
3. The lofts where the beds are located suffer from light bleed if certain downstairs lights are turned on.
If those things don't bother you, then book this place. It's a great location to explore Ximen and come back whenever you need a break. The host responded quickly and even accommodated our request for an early check-in. Even little details like a portable wifi router that you can use during the stay create a positive experience. Overall, a fun place!
