Bernat was a great host and helped me check in later at night when my flight got in. He was super helpful in terms of where to go around his place and was extremely friendly. The place is very clean and the same as in pictures. The area was not as a great as I thought, but if you walk 2-3 blocks in either directions it gets much better. The neighborhood, the Mission, in general, is amazing. Bernat's place was walking distance to so many great restaurants and local eats!
The apartment faces into a small patio which muffles the street noise, which is great, but this causes not much sunlight into the apartment - which is okay since I didn't spend all day in there. The only real complaint I have is that the neighbors are very loud sometimes and not considerate; playing loud music early in the morning and kids running up and down the hallways shouting very loudly.
Other than that, the place was amazing and I would recommend staying there.
