We had a lovely first trip to Barcelona. The apartment is exactly as described, modern, and very well thought out. It is perfect for two people. The host (Helena) was very responsive and went above and beyond to address a minor difficulty we had with the washing machine. Entry to the building is secure. Transport/airportbus/redbus are all close walking distance. Due to the acoustics and layout, there is some noise from people coming and going from the neighbouring apartment and also a low rumble every now and then from thr subway (i think). Neither were particularly bothersome to us.
