I stayed here for a few nights in April 2006. I stayed in a Mercure before this hotel (la Défense). Those hotels aren't supposed to be as nice as Sofitel. I thought the Mercure was much better!.
The rooms in the Sofitel porte de Sevres were really spacious. There was a minibar, large bed, a/c, clean bathrooms. Basically it had everything a four star hotel is supposed to have. On the other hand the paint was starting to peel and it looked a bit rundown. I thought the prices were way too high. I don't know how they dare to ask so much money for a room. I don't think this place is good value for money. The lounge is really nice and the service is excellent. The location is good too as it's near the stock exchange. This hotel is located in the south of Paris.
