This is an excellent place to stay, right in the heart of Sevilla's historic district. The place is very charming, with private access off the busy square. Within a 10 - 15 minute walk from places like the Real Alcazar and Sevilla's cathedral, I highly recommend this place for people looking to spend a few days taking in the sights of the city.
One note for anyone driving: it is a bit difficult to access if you have a car and are not used to driving through historic Seville. I recommend locating the parking garage by the Plaze de San Pedro (shows up as Parking Imagen in GPS), parking there, and walking to the apartment.
