We stayed at Plaza Catalunya for 4 nights late May. It is in a great central location. We arrived very late and James was extremely helpful in arranging some-one to meet us and get us into the room.
The Aero-bus from the airport stops just around the corner. We arrived after 10.30pm and left on the 5.00am Aero-bus. Get there before 5am as the two buses filled up quickly.
During our stay James was most responsive and helpful on any questions or issues we had. Traffic and people noise were not an issue as there were double glazed windows. We had 4 adults, the one bathroom was a little tight but we were prepared for that as the central location and convenient transport were our priority. The first bedroom was spacious with 2 beds. The sofa bed in the lounge was adequate. The second single bed was in a separate room but not made for anyone over 6 foot.
The apartment is located on the 6th floor with the lift starting at the first floor. This didn't cause us any issues.
There is a little mini-mart two doors down for any basics items that you may need - local prices.
The apartment was clean and tidy and suited our needs. We would definitely stay at Plaza Catalunya again.
