If you are looking for a unique or boutique hotel with to stay in Shanghai and you want to stay away from the usual Hiltons or Holiday Inns, I can recommend Gallery Suites, right at Heng Shan Road (aka Party Street).
The hotel is converted from an old apartment built in 1933. If you want a taste of Old Shanghai during your stay here, this is it.
It is all suites and every room has a different design. Though a bit old, the rooms are reasonably spacious for a suite with a proper and full size working desk which can double up as a dining table for takeaways or hold a small discussion.
Let me show you some pics:
