We met Jorge's Brother Alvaro just at the time arranged by whatsapp. He showed us around the appartment and gave us some nice advice for things to do in Sevilla, and also the address of supermarkets and (most important) a good tapas bar. Thanks again, these were great!
Parking was surprisingly easy, even though Sevilla is a typical spanish city with a terrible parking situation, but Alvaro showed us an area right across the house where we left the car for several days, without any ticket.
The appartment itself is on the fourth floor of a beautiful old building with a very nice feeling to it. Within the appartment, the two levels give plenty of room, and even though we had 41 deg at that time, the 3 (!) air-condition devices made it tolerable. Everything is available in the kitchen, and also in good condition.
What is definitely the best part of all is the location - just a quick walk to the Alcazar, the Cathedral, and all the major areas. We especially loved the area around the Puerto de Carne where many nice bars can be found.
