First and foremost, Adrian and his son Felix were very helpful the entire month I was in BA. They're friendly and were knowledgeable about the neighborhood, how to use public transport, sightseeing suggestions, and all the questions I had. They were also very accommodating with some appliances I'd forgotten at home (iron, blowdryer, ironing board, etc.) Checking in and out of the place was a piece of cake.
The place was cozy and has a vintage charm. It's on a pretty quiet street and close to the subway and all the Palermo bars, cafes, and eateries you'd want to go to. That said, the mattress and pillows could be replaced. It would also be great if the curtains covered the entire windows because it's very easy to see up into the place at night. You can also hear just about everything the neighbors are up to, but you can get around that with some earplugs or white noise.
All in all, I enjoyed staying in this place, and it was a pleasure to have Adrian and his son as hosts. I'd recommend them in a heartbeat!
