Toni was an excellent host who awaited our arrival and provided a thorough orientation to the apartment in both Spanish and English. He also made it clear that he was close by and available if any problems arose.
The apartment was as described in the posting -- superb location (close to public transit and stores; it was even walking distance to key points in the city), quiet, modern, clean, and well supplied.
The only negative was the inconsistency and weakness of the WiFi signal -- disappointing given the high quality of the other features of the apartment.
