We stayed in Jesica's Airbnb for about 3 weeks and had a wonderful time!
It was spacious, had everything we needed, great kitchen, nice dinning table, TV, couch, comfortable beds (two queen-sized), enough towels, fast WiFi etc.
Parking was a little tricky at first (it's street parking) but we figured that there was plenty of parking on Ocean Blvd - so we just parked there. Be aware of street sweeping days, though.
Having bikes was wonderful! Long Beach is very bike friendly.
The Airbnb is, indeed, only steps away from the beach. Restaurants were also very close (5 minute walk) - it was wonderful to have a place where you are not so car-dependend (which is often the case around the LA area, I think). Of course, to see many key tourist destinations around the area, you'd still need a car. But the place is still in a very great location for that since a lot of places can be reached fairly quickly (depending on famous LA traffic of course ;)).
The neighborhood felt very safe to us and it was overall quiet. However, light sleepers should be aware that you can hear your upstairs neighbors quite loudly (I don't think they were being loud but just their regular footsteps etc. where very noticble in the Airbnb) as well as construction outside. I did not bother us too much but bring earplugs if you are a light sleeper :)
The check-in/out and overall communication process was smooth and we had no issues at all. All in all, I'd recommend this place and would absolutely stay there again!
