We couldn't have picked a better Sevilla apartment and host family! We were warmly greeted on time by Jose and his wife and shown the apt and immediate vicinity including supermarket just a half block away.

The apartment has great style and flow, privacy and security, was sparkling clean, we'll equipped, with great air conditioning, and the most perfect location for touring Sevilla on foot.
Not really knowing distances before arrival, once here, we found that everything we wanted to see and do was never more than a leisurely 6 to 10 minute walk away. We kept saying this to each other as it unfolded.
The Cathedral and the Alcazar were at most 6 minutes accessed straight down our shaded Alvarez Quintero, I would call a cobble-paved lane rather than street. Sometimes, we walked down the wider and sunnier Calle plaza de San Francisco, or C. Francos again straight gown to the Cathedral. Other times, we walked the opposite direction on all three Calles to get to Plaza Encarnacion or plaza Alfafa where we ate at La Bodega or Bar Alfafa.
The shopping district around Calle Sierpes was maybe 2 minutes away with locals and visitors parading and using as a Ramblas. Tapas and coffee bars and restaurants were everywhere including on Alvarez to the left, across the street, in the Plazas El Salvador, San Francisco, de Jesus, basically anywhere we turned. Better quality and lower priced food was a block or two removed from the street in front of the Cathedral, named Alemanes.
What great hosts, apt, and city!
