I stayed at W=A Tower Shanghai for 2 nights recently, few days before the Grand Opening (18th April). Here are some random thoughts.
1. Tower entrance is not easily located by taxi drivers. In order for you to be dropped off right in front of the hotel entrance, a taxi has to make an entry into parking area (?) by turning right, then turn right again. It's not the easiest way to arrive, particularly if you don't speak Chinese and have no idea how to get to the porte cochere.
2. Since I was such a dummy, I agreed to be dropped off on the corner, thus had to walk with my luggage and got ignored by the doorman. Once I was inside the hotel, porter grabbed my luggage immediately.
3. Check-in was a bit longish, staff visibly nervous, should be better soon.
4. Sometimes I got greeted by at least 7 or 8 people in the Lobby and twice found the Concierge desk to be deserted.
5. Room's spacious (view of Westin Hotel) and features all the bell and whistle of a 5 star property. I love the 'magic window' between room and bath that turns clear/opaque with a switch of a button and the fabulous Toto toilet (similar to Park Hyatt Shanghai's)
6. Dinner at Pelham's was rather disappointing. The chef was kind enough to say Hello after the meal - but the food itself (taglietelle with pork shoulder and braised short ribs) was a letdown. Room's pretty.
