PROS: The location can’t be beat if you like being in the middle of the action. Lots of restaurants, bars and public transportation. There is a local market nearby and a carrefour 10 minutes away (walking). We traveled with my parents, sister and 2-year old niece. We could reach Plaza Olavide within 5 minutes and my niece loved the playground - and we loved the bars and lots of people seating outside, eating, drinking and enjoying themselves. The place is well furnished and Miguel was super responsive every time I had questions.
Cons: Two full flights of stairs to reach the apartment, there is p let air conditioning in the living room (which was NOT a problem for us, might make it more difficult for those sleeping in the suite in the summer). There was some noise from people partying on Friday night, which is expected for a busy !(and fun!) area, just be prepared. I slept in the sofa bed in the living room and the noise did not bother me, but it did keep my sister up for a little in the first bedroom.
Overall, I STRONGLY recommend the neighborhood and Miguel’s apartment. You really feel like a local and have a much better experience than staying in touristy areas. I would definitely come back and stay at his place again!
