Goska and José were, no exaggeration, the best hosts I've had the pleasure of staying with. I've stayed in quite a few places, but they definitely lived up to the title of "superhost."
I'm happy we got to talk about what they do and how life in Madrid is. They also pointed me to good supermarkets, and even recommended (and shared) some wine with me. Their dog Jazz is sweet, too! I miss the little guy. He barks a lot, but don't worry, it's only because he's worried you'll get from his food, haha. So a trick I figured out is to have food with you, so that he's quiet. :)
The neighborhood is awesome, with shops right downstairs, and a bus and metro station just 1 minute (or less!) away. Retiro park is right in front, so whenever you feel like a stroll, all you have to do is cross the street.
Their place, especially the room, is actually BIGGER than what it seems like in their photos! So that was a really nice surprise. :)
Definitely recommending them heavily for anyone who goes to Madrid. :)
(Thanks again, Goska and José and Jazz!!!)
