Overall, a GREAT place for a long term stay for a single person or couple. Definitely recommend.
Wi-Fi - both my bf and I worked from home the entire time, and I only had issues with video calls maybe once with both of us on. The Wi-Fi is relatively fast and we had no issues with it.
Amenities - the airbnb is definitely stocked with almost EVERYTHING you can think of, no need to bring any extra toiletries. We also made use of the gym (very basic stuff, no treadmill), and the hot tub. The gym is always empty when we went, and there was only 1 time we had to wait for someone else for the hot tub. Also covered parking in a garage was a huge plus.
Location - CENTRAL location!! North Park/Hillcrest were within walking distance, but it was still easier to drive. The zoo and all the museums are also super close, which was great for outdoor runs! Literally everywhere we went was like a 10-15 minute drive (downtown, little Italy, the beaches) and La Jolla was only a little more (20 min).
Host - Katherine was super responsive and very helpful via messages. The property manager (who we had to deal with in person) I did not care for as much.
Other - There was a bit of dust everywhere the first day we came but we cleaned it up and it wasn’t too much of a problem after. The pillows weren’t my favorite, but I always bring my own :P The decor also wasn’t my favorite, and it didn’t feel very home-y, but it fine for a month for me *shrug*
