Hector's place is close to the metro, a mall from a converted bullring with excellent rooftop views, and the Miro park. Definitely see the sunset from the mall. Very easy to get to using the 46 bus or the Aerobus.
He is a super nice, friendly guy. Gave good suggestions on where to eat. Sent screenshots of maps to help you find it. Tartelas around the corner was great, I went there twice. Flexible check-in was helpful.
The area was less touristy, which I appreciated. I recommend staying with Hector.
