Juan and I were in constant communication prior to our arrival in Spain, and prior to our arrival in Seville from Madrid.

He arranged a trusted private car driver - Carlos - who picked us up at the Santa Justa station.

The place is the most centrally located, 3-4 mins walking from the cathedral. The neighborhood is packed with many restaurants and tapas bars. One of the best meals in Spain we had was in a small restaurant very close to his location.

Juan advised us well about seeing one of the best flamenco shows at Los Gallos. This is also 3-4 mins walking distance from his home.

The house was built in 1868 - so it is aged. When we entered, it immediately reminded me of my grandparents old home in Kolkata, India.
But the inside is clean, and there is one room on the ground floor, and two rooms on the second floor (1st floor European system). Our room was nice, with two twin beds, table, and a dresser. The bathroom is close by and was clean. It was shared with one other guest (from Argentina, now living in Spain).

Juan helped out with carrying our rather heavy luggage up one narrow flight of stairs. When we found one of the table lamps light bulb was out, he replaced it promptly!

Overall, it was the best possible location and great host.
