Montserrat

Disliked: Staff & service
After paying so much money for a 3 night stay I was charged an exorbitant amount of money per day just for them to open the sofa bed that was already in my superior king bedroom reservation for my 13 year old daughter to stay. I mentioned that I was coming from a Marriot hotel in Paris and was not charged extra and the front desk lady was rude saying not all marriots have the same owner! I thought this charge was outrageous, just to open a sofa bed that was already part of the room already. I am never again staying at a Marriot hotel chain.

Highly recommended!

Really enjoyed my stay at the hotel. It's located in the nicest part of Bracelona, along the Diagonal Avenue. It's useful that the hotel is situated right next to the beautiful L'illa Shopping Centre (the mall's food court had an impressive variety of culinary options). Rooms are large and nicely decorated. Hotel staff are overall polite, professional and very helpful. There is special attention to cleanliness. Breakfast was nice, although the variety of the main courses could be improved. Again, the waiters were efficient and friendly. Would definitely want to go again.
