How about Shanghai Yashige Hotel Apartment?

Yashige Hotel Apartment is a well-known brand, and has lived there several times. There's nothing to say about cleanliness. Mainly there is a kitchen that can cook by itself, and the supporting facilities are very complete, which is very suitable for friends who travel on business or in groups. There are many Ascott serviced apartments in Shanghai, which are basically covered. Personally strongly recommended.
