We actually did not meet Miguel, as there was no need to. Miguel had arranged for an easy start of our visit to his apartment.
His pre and post communications were very good and fast.
We loved his apartment and found it as per listing. We decided to stay and sleep in the downstairs bedroom, because of the great heat in Seville during our stay (about 40 Deg C. The place downstairs was very cool because of the thick brick wall and required the air conditioner only once for a hour or so.
The apartment is ideally placed in one of the many little streets near the Cathedral and the canal. We did not use any public transport except coming and going to the train station), due to the good location.
When we are returning as planned for next year, we shall try to rent Miguel's apartment again.
