Stayed for 5 days in November 2012, the king size bed was wonderful, free wi-fi appreciated, the room was facing the street but super quiet. Even though it is a fantastic old chateau, it was closed for many years and recently bought and renovated (everything works well and is very upmarket) but they have kept the charm and look of an old chateau. It is quite magnificent. The bathroom fixtures reminded me of a beautiful 5-star hotel. The staff was truly amazing, especially Pablo, very helpful, his English was excellent, suggesting restaurants and helping us to make plans.
The location is okay but not walking distance from anything, however, the bus and tram stop right outside the hotel and an all day transit pass (4.50 Euros) is a total bargain, you can buy it at the newsstand outside the hotel, you can jump on and off busses, trams and the Metro all day. Tried the breakfast buffet one morning only, it was unbeleivable, fantastic assortment of pastries, meats, cheeses, etc. etc and they will make you an omelette to order. Too pricey however at 25 Euros per person, we preferred the bar across the street, coffee and a croissant for 4 Euros.
