I stay this January for two weeks in Natural Ville. First we miss it when we drive down the langsuan road. For orientation is the next one after Centre Point Langsuan. The sky train stations Chit Lom and Ratchadamri are not far ( 500m ).
I was realy satisfied. I stay in the suite with 59sqm. The room looks new and modern with all usefull amenities. The rooms look realy like on the fotos on http://www.naturalville.com. Just the surounding fotos from the building they photoshoped to much green around.
Service was also good and professional. Pool area and the gym is ok. The Hotel SPA is also great. The have rebuild the whole 14 floor for this
The French (LE NOTRE) restaurant was for my taste to hi-so and overpriced. But the patisserie is the best one in Bangkok If you want food in the room you must order over food delivery service from another restaurans. ( have two index books in room)
I would always tend to go with the Marriott Mayfair directly across the road from Natural Ville. IMHO the apartments are of better quality as are the amenities, to be fair though the pool arrangement at Natural Ville is better for sunbathing and the spa looks pretty good.
I just think Natural Ville is overpriced for what it actually offers, more expensive than the Mayfair without many of the mayfairs facilities. Cafe Le Notre is quite nice though. Another good place to stay in Lang Suan in Cape House, this offers more room than Natural Ville and similar facilities at a lower price. Another good alternative in a similar area would be Centrepoint Wireless.
