Easy 5 stars for this one.
It is everything the pictures suggest and more. It's actually really quite spacious, gets a lot of natural light (much more so than the pics suggest), and is located in a great location. Plenty of tapas bars and great restaurants within 5 minutes. The Duo tapas place is about 1 minute away and it was always busy - for a reason.
It's an easy walk into Centro, but if you're not keen on that there are tons of Seville bike rentals out front, or electric bikes via Lime, which gets you to all of the major attractions really quickly. It took about 20-25 minutes door to door walking from the apartment to the Alcazar and Cathedral.
As other reviewers have mentioned, even though this apartment overlooks the Aldameda de Hercules, the bedroom is completely isolated from any of the noise.
The ACs worked great, the kitchen has what you need to get the job done, and overall it is a great spot to call home while in Seville.
The ONLY thing I'd suggest is to be wary of the gate when exiting the apartment. Where there was once a doorknob there is now not a doorknob. To open the gate requires a pretty good deal of finger strength to turn the little attachment where the doorknob used to be. This was actually quite tricky at times, and required pushing down (as in literally down from above) with pressure and then turning to the right and pulling the gate at the same time. Hope that helps. Otherwise you have to try fumble through the gate with your key to unlock it from the street side.
