I did not meet Juan but with Mariluz I had an nice effective checkin.
If there is a center in Seville you are there. The flat has very good value for the price, spacious, wonderful views, good kitchen, very good bed. The only thing you might miss is a real table, but the big coffetable did it for me. There is a big sofa you can relax on. A little noise from the bar at the corner stops at midnight and its closed on Sat Sun, after that very quiet.
I loved especially a bird in the neighbourhood, whose sweet soft sounds replaces the watch in the morning.
