This is the first time staying at a Mandarin Oriental hotel, which is why anytime I need a Five Star hotel it will be with the Mandarin Oriental chain. My wife and I were very impressed with the all of the staff, always there to help you and so knowledgable. Staff in restaurant were there for you if you even thought of something you needed. Dining was out of this world, as well as the decor in rooms and hotel. We stayed there 4 days and traveled north but altering our plans to go back and stay our last 2 days. We could mention names of special staff but would not because we'd leave someone out, what training by management. Beautiful hotel in a great shopping area in a great city.

Great location, great service, great design. Just a shame that the double glazed windows don't seem to work. I stay in a boulevard side room and the window might as well have been open the noise was the same. Strange that a hotel that was quite recently built wouldn't use triple glazed window as the noise from the traffic is quite bad!

On another note Moments restaurant is fantastic. As are the concierge, every recommendation was perfect, just what we had asked for. All the staff were very friendly. Breakfast was also really good, really good Buffett and perfect cooked breakfast. I've stayed in a few MO hotels, Barcelona certainly has the best chefs and friendliest staff.

Stayed for only 1 night in July, 2012.

I was pleased with this hotel choice. Of the several top-end options in Barcelona, the MO seems to be the clear winner if you want to be in the city (as opposed to being at or near the beach area.

The MO is situated right in the prime area on Passeig de Gracia, which is a huge asset. It is in the midst of all sorts of great shopping, restaurants and one fo the Gaudi houses. The location can't be beat.

The hotel is VERY contemporary, but well done (as compared, for e.g. a 'W', which generally feel cheap and Ikea-like to me). Out room was spacious and well appointed. Cocktail serviceright to the room was complimentary with our suite...a nice touch. The staff at the Concierge desk is very good. Suites also have butler service, which was quite helpful. We only ate breakfast at the hotel, and I have no complaints there.

the roof top pool deserves special mention. It is small, but designed in a very cool, contemporary, out-door space with very cool city views looking out beyond a gorgeous rooftop pool. Very nice spot.

My only complaint with the the MO is that the views to "the garden" are not all that desirable. Basically you are overlooking the outdoor space in the back of the hotel, which includes a somewhat unattractive collection of the backs of buildings. It's not terrible, but not a beautiful view to look at either.

This property is about location, location, location. There are building works now in November in the building next door, so ask when you check-in for a quiet room if that is of concern to you. The spa needs a refit in the pool area (or a good clean). Rooms to international standard and comfortable. Streetside rooms can be very noisy also at nighttime so ask for a garden room.
