Everything is fine in the hotel except that there is absolutely nowhere to have dinner. There are two restaurants in the hotel itself, both expensive and so-so in quality, and the nearest place where you can have a snack is a kilometer away on foot. But the breakfasts are on top.
One of the best Marriott hotels. It is quite far from the city, but 5 minutes walk to the metro. The hotel itself is very beautiful, a pleasant conference room and not a bad kitchen.
