First: There is NO pool. Second: There is no GYM.
If you book because they advertise this, it will be a bad surprise.
Rooms are okay but not outstanding. Our first room was loud as it was facing the street and insulation between rooms is also bad. It also had a bad smell. We changed to another room and floor. First they wanted to give us a room with only a tiny window, but we insisted on a better view and finally got it. The staff is helpful and polite but slow and not really customer oriented: eg why don’t they hand out free breakfast as an apology for all those things going wrong? Well, can’t blame the young staff. They are nice and even speak good English but the hotel management seems to be a problem.
Finally we did not extend our stay after 3 nights (planned 11 more nights) simply for these missing points one can get much better accommodation in Shanghai at a better value price point.
Lesson learned: never assume the hotel description is accurate! See the place, before booking long term stays.
