Jose María (JM) was a wonderful host. In addition to being very friendly and providing excellent information about Seville (including a great recommendation for a flamenco show), he provided provisions that my wife an I have rarely found in an Air B&B such as water, juice, tea, coffee, milk, jams, etc. The place was definitely well stocked.
The apartment was as advertised and well located (within minutes of restaurants and attractions). It was clean, very comfortable (especially the bed), and suited my wife and my needs just fine (though we did not make use of the kitchen during our stay). The only issue we had was with the air conditioning. The apartment is on two floors, the second being the top floor. The central ac does not work well on the second floor due to the apartment's construction. JM provides a high power fan that goes a long way to remedy the issue, especially if positioned well, but we found it hard to regulate the temperature at a comfortable level.
My wife and I would definitely stay at JM's apartment again if we were to return to Seville.
