This is a very fine property. Here was my experience.
1) Location. It's next to a decent size and beautiful park. It's surrounded by two rivers (or water paths), and along the river are some shops and restaurants. It lights up very pretty at night. Also right across the street is a major mall with IMAX. Overall, an excellent location that has plenty to do all within walking distance.
2) Check-in. As you walked in the ground floor lobby is extremely small because it's not the lobby, although concierge is there. Here is the confusing part. You have to take an elevator up to 35th floor, and as you come out you will be greeted with a decent size lobby and a big check-in area, also part of lobby bar. Of course if you are Platinum elite, then you would need to proceed to ANOTHER set of elevators (across) and head to 52nd floor where the Executive Lounge is.
3) Lounge: It's "big" as it's shaped like a thin rectangle shape that stretches around the building's corner. Check-in desk is by the entrance. Because the space is really stretched as a rectangle shape that wraps around a corner, the food and drinks placements are stretched out as well. You will see salad/fruit on a table, with hot plates against the wall, with more food dishes around the corner (not visible to you if you don't turn the corner), and then refrigerated drinks next to it. Also because of this lounge shape, chairs and tables are limited and some seats will be so exposed that you feel really close to people walking by. The best seating for privacy is a set of table with sofas directly ahead of the entrance (they've put a blocker for privacy) and another set of sofas around a table to the right of it.
4) Services and Staff: the usual Asian (Chinese) friendliness and eagerness to solve your issues. However, English is very limited so again, if you don't speak some Chinese, you can expect a relatively hard time of communications. Get that Google translate ready.
5) Restaurant: here's the pet peeve. It's really hard to get to from your room. You would need to take a first set of elevators down to 35th floor. Then, switch to the elevator that only goes down to 1st floor (literally only 35th floor and 1st floor buttons in the elevator). After that, swing around to the right, turn a corner, and you will find a third set of elevators, that is the one that leads to the SENSES Restaurant (5th floor). BUT, that's not the end of the story. In typical Wenzhou style, the SENSES restaurant ONLY HAS BIG SUITES that seats 10+. Meaning if you are just one or a few people, they will NOT seat you in the suites. The best they will do for you is redirect you to a Hong Kong restaurant next door, that has open seating, and you can order food there. Now, they won't tell you this, but you can order SENSES food and eat it there, or simply order from the Hong Kong restaurant menu (limited).
6) Room - upgraded to a suite. Two gigantic size flatscreen TVs. Gave you a traditional Chinese tea set (kettle and cups). Nice soft in living room with a big stretched table. A cushion seating against the windows in the bedroom, with an attached table in the middle. The only stinker is a very small round working desk. Can barely fit your laptop, cup of drink, and your mouse. Must be the smallest table in a hotel I've seen (including low-level hotels). Guess they don't expect people to actually work in their rooms. Also, not full carpeting. A round shaped carpet in the living room that's under the desk, and a round carpet under the bed. As a carpet lover I hated this design, but if you like hardwood floors than this room's for you.
Overall, a very new (barely a year old) and very nice property. I used to stay in Sheraton Wenzhou, but will definitely only stay in Westin Wenzhou from now on.
