Excellent level of service, Frédéric was very responsive and helpful before we arrived. The flat was immaculate and extremely comfortable and quiet, very well located 5mn walk from the metro (subway/tube). 1 stop away from the Sagrada Familia. Both Frédéric and his colleague Jean-Marie were very friendly and helpful. I would highly recommend!
I would also recommend to future Barcelona visitors to plan ahead and book ahead visits to the most sought after attractions such as Park Guell, Sagrada Familia and museum Picasso for example. All these visits are "time-slotted".
