We just spent 6 nights in Manuel's apartment. As so many have said, it is the perfect location and Manuel is the best of hosts. We toasted our trip with his delicious homemade sangria. His excellent recommendations for restaurants, walking tour, and flamenco (for which he made the reservation), as well as his insight and enthusiasm for his city helped make this one of our best and most complete trips. I can't think of anything that went wrong and he was always accessible for information. His apartment was well stocked with the basics foodwise, as well as plenty of toilet paper. Having a washer and a dryer was a great convenience. The dryer's cycle was much shorter than our past experience with European clothes dryers.
Also, on the few nights that were chilly, the heating unit worked very well.
His additional service of picking us up at the train station, and bringing us back for our return was extremely convenient.
Should we return to Seville, we definitely stay there again.
