Right in the middle of the Ximending area with plenty of options of everything. There are several gyms and convenient stores,too. More importantly, the staff member Zhen (Jan?), young gentleman with glasses who works in the afternoon is very kind. He is professional and very helpful. Other gentleman named Eddy is very friendly, kind, and a positive person as well.
Unlike some accomodation, they provide free towels and slippers. For this area and these amenities, you can't go wrong.
I wanted to stay longer but sometimes rooms are very cold. So, if you easily get cold, just bring long sleeve clothing. You will be fine.
