The apartment was fine if you are inclined to stay up and party till 1.00am to 2.00am because the excessive noise would not impact on your rest. If you like an early night and lots of sleep this apartment may not be right for you.
Wifi was virtually unusable with very poor signal strength and bandwidth. Basic amenities provised, reasonably hard and low bed and very ordinary pillows. Overall a disappointing stay due to Lake of sleep impacting on enjoyment of Barcelona.
