In November 2010 we visited Spain as a group and during the trip in Barcelona we stayed in Catalonia Barcelona Plaza Hotel. Rooms were designed perfectly, quite enough and the outisde view from the windows were beautiful ! We only got the breakfast so I can only tell about it. You are free to eat anything from the open buffet. Wide variety of food available. The most important thing is the hotel is located just in the heart of the city. Bus stops and subway stations are just 5-10 steps away from the hotel. So you dont have to worry about the trasportation. I really liked the hotel and if I travel to Barcelone again I sure choose the same hotel for accommodation.
Note: I had to choose March 2013 as our travel date because previous dates are not available to choose ! Thats a mistake of the website. Because not all members are travelled in 2013 or 2014. I travelled in 2010 but there is no such option in the box.More
