This Airbnb somehow exists in the greatest locations, right in the middle of a bustling plaza with food and drink, but is absolutely silent inside. It's perfect. Very comfortable with the AC in the Seville heat, and a short walk to the old town.
I highly recommend staying here for anyone who wants to experience different parts of Seville. Alameda de Hercules is a really fun spot to be, and its a short walking distance to all of the touristy activities as well.
