Top notch room, wifi worked, nice desk, upscale bathroom with both bath and shower, included rain forest nozzle. Staff is very friendly, usually greeting you with a smile and saying "Good morning," even when just walking by. No gift shop. Nice selection of sandwiches, sodas when going out for the day. Lucas, the concierge, was awesome. He knew I like Diet Coke and made sure I had one before leaving on a tour. The bar/cafe is iffy--for me. Live music, very loud, and hardly anyone in the cafe ... I think the music drives people away. It did me! I didn't want to have a nice drink and meal with that music pounding in my ears!! So I went elsewhere. But overall, top notch place, and great staff, with a working knowledge of English.

Mixed experience: not sure if I would stay again.
This is considered a "5 star" hotel in China. For a large international brand, there were issues: 1. Front desk staff was friendly and helpful, with most speaking proficient English. Sven was especially helpful. 2. Restaurant and wait staff were not as proficient with English. 3. Public areas were looking worn-out/dated. Chairs in restaurants were too low for the tables. 4. Food in restaurants was good, but service was slow. 4. Room service was fairly priced, but repeated things like forgetting silverware, condiments, or incomplete orders made the process not enjoyable. 5. One night, my child had a nose bleed. There was blood on the linens. Upon check-out we found we were charged an extra "cleaning fee" for this. While this type of charge may be common (?) in China, I have never had it happen in Europe, the United States or other Asian countries. For a minor incident over a 9 night stay, I thought this was a bit much. I had never had this happen to me in China before.

Location location location
Check-in is fast and a room with great view is assigned. Staff is very efficient and nice. The hotel’s decoration is golden tone and it reminds me China’s 1980s’ Canton area vulgarly decorating style. The room is a business suite and equipped with desk, basic business tools such as stapler, paper clips, eraser, etc. Internet cable is also ready. WiFi is free. However, they still use 1980s’ electric kettle and instant coffee. There is no brand name for anything. Location is terrible. It is not too far away from major attractions but public transportation is limited. It is not walking distance to anywhere. Also, because of the one-way traffic next to the hotel, it is very difficult for the local Didi drivers to find where the entrance is. This city has a dedicated lane for bike riders. However, because cars double park so frequently and occupy the bike lane, bike riders often have to risk their life being hit by a car.

False advertising
There are multiple problems with this hotel. Most importantly, the rooms we rented were supposed to be 45 square meters large but the truth is that they were less than half the size - clearly false advertising - beware! Relatively speaking, the rooms are tiny. In addition, the service was well-meaning but poor, the restaurants were mediocre, and extra purchases were expensive (a bottle of water was the equivalent of more than $3, a small latte the equivalent of more than $11 ....). I would recommend other hotels in Wuxi that are better.

Beautiful hotel
I stayed in this hotel twice and both times it delivered to the best of my expectations. There's nothing I dislike about this hotel. It has great service, very good food, especially for westerners. The Paulaner restaurant in the lobby is awesome. It serves very good choice of German-style food. The staff speaks English. The internet is free, and you can get higher speed wired access (four Mbit up/down) for a very small amount.
