Stayed at the hotel for 3 nights over the weekend for the Grand Prix and overall we were very impressed.
We had booked 2 rooms on points for 3,000 per night for the weekend. The hotel was sold out on our first night due to arriving F1 fans, as well as a large cruise booking that had booked out a lot of rooms. Both rooms were upgraded to adjacent Preferred rooms on a higher floor. These were comfortable and spacious enough and traffic noise wasn't a problem due to the high floor.
We found the beds and pillows very comfortable and had a great night of sleep each night as a result. The bathroom was well stocked, above and beyond what I normally would expect at an SPG hotel.
Breakfast is adequate, but not brilliant. There is a selection of cold meats, cheeses, pastries and breads, as well as cereals and yoghurt. There are also some hot options, but as claes059 mentioned earlier it isn't exactly packed with flavour either. For a Platinum amenity for 3 days, it was perfectly fine though.
There is a gym with modern equipment on the top floor. The space is limited, but there are 4 brand new machines and some free weights. It does have floor to ceiling windows though, offering a great view across the city and to the beach area.
We really liked the area that the hotel is in. The Glories shopping centre is across the road and offers shopping, dining and the likes of Starbucks and Carrefour if you want to stock up on food. The Metro station is only 10 minutes walk away with the direct train service to and from the airport. We walked to Segrada Familiar in about 25 minutes, as well as to the some of the main tourist areas within 30 minutes which made for a pleasant stroll. The beach is 15 minutes walk away and there are plenty of local restaurant and bar options on the way.
The hotel can't be compared to the likes of a W as it is at a different end of the scale, but if you want a clean, comfortable, modern hotel in Barcelona, then I would recommend it, especially for the price in cash or points at the moment. We would definitely choose to stay here again in the future.
