We loved our stay in Barcelona! This apartment was in a great location - within easy walking distance of lots of tourist spots and with lots of 24 hour shops right downstairs. It was really good to have the balcony although it was quite noisy out there due to the traffic. The traffic was also very loud in the front bedroom (the double room) so bring your ear plugs! It was really great to have the air con - there were individual units in each room and it worked very well. There was plenty of room in the apartment which was immaculately clean but a little tired round the edges.
Overall, we really enjoyed our stay and would definitely recommend it!
