Had a great stay right in the Santa Catalina area. The apartment was spacious, and on the first floor so just one flight of stairs. It was just me so I didn’t use the second bedroom for sleeping, but this would be a good spot for four guests. The bed was super comfy. The kitchen is pretty well equipped and I was able to cook some good meals with great ingredients from the local Setas market. Check in and check out was easy (I got some helpful tips on the keys and the apartment) and the location is great and very central. All of Seville in the old part is basically set up for walking so buses are a little limited, but everything is within 20 min walking distance, or you can rent the shared city bikes. Lots of great bars and restaurants in the area. Pretty quiet by Spain standards, and close to a lovely wine store as well. Would highly recommend!
