I stayed at Andreas flat for one week and I had an awesome time! I felt at home as It is well situated, sunny, has plenty of room and balconies where you could chill and look onto the daily life of Sevillanos. I loved the simple but retro design with the typical andalusian floor tile.
The communication with Andreas was perfect! he was very responsive and gave me every info I needed plus I could check in earlier, muchas gracias!
Small note maybe for the next visitors: the flat is situated next to the church and could be busy/noisy during peak time but it didn't bother me.
