My stay at Mario and David's was my first Airbnb experience and I could not have asked for a better one. Their house was charming, clean, tech-y, and very inviting and the room I stayed in was very cozy and comfortable (the bed and the pillows were really soft and cozy it was hard to get up in the morning haha). It (the room) had a sort of separate hallway and door which they told me I could close for extra privacy. Bathroom and kitchen were very neat and clean and they were kind enough to let me to use their kitchen when I needed to. My conference was at The Grand Hyatt which was around 30 min walk from their home, which isn't bad at all since the walk is scenic and their neighborhood is really charming as well (and you'd be able to pass by some cute cafes along the way). Uber from their place would be around 10 mins away from the convention center area and around 15 mins away from the airport (without traffic). These guys are really friendly and great to talk to so don't hesitate to strike a conversation with them or ask questions. They were very helpful when I asked for tips on where and what to see around San Diego. Their dog, Philip, was great as well; was so chill with me the entire time. Overall I enjoyed my stay and I would definitely book again the next time I visit San Diego! :)
