I've stayed in that neighborhood a few times, but never at the Wyndham (and, following my bad experiences with their corporate customer support last year, I'll probably try to avoid them in the future).

The high-rise Hotel Okura is quite passable and equally close to RAI, though some rooms are dated. The citizenM Hotel, on the other side of the park and also equally close to RAI, has been getting good reviews on TripAdvisor - I have not stayed there but would consider it if I needed to be near RAI. I've also rented apartments in the area with good success. It's a pleasant neighborhood. For my own purposes, I'd rather be much closer to the center of town, where good hotel choices abound.
