This is a very comfortable, big place to stay. You can easily walk to the gaslight district and there are two grocery stores close by (one, Grocery Outlet is only two blocks away). The kitchen is well stocked with all the basics you would need if you plan on cooking yourself. Big fridge/freezer. There is a combo washer/dryer but I didn't use it. Shower water is hot and with excellent pressure. Netflix is free on the TV and there is wifi. Communication with the owner was very responsive. Check-in was via electronic lockbox and very easy to use. There are a ton of windows so lots of natural light. Working the thermostat was very easy.
Some things to be aware of:
You need to go up approx 1.5 flights of stairs to get to the apartment. Also, parking is across the street in a secure garage but I was able to park closer to the apartment on 11th street when I was unloading/loading my car by putting on my flashers and parking on the street. Also, due to preponderance of one way streets in downtown, you will have to drive a few blocks out of your way to get to the garage; seemed weird at first but I quickly got used to it.
The apartment is located on a very busy street so there is a lot of traffic noise and some minor construction work down the street. Also, a roller garage door is directly below the apartment which the other residents use and you can hear that going up and down but it only happened a few times when I was there. By the third day I didn't notice the street noise anymore but if you are super sensitive, you may wish to bring ear plugs. I couldn't hear the neighbors at all.
Airport is only a 15 minutes away and I think all of the major tourist attractions are only a 10-15 minute drive away.
The bedroom and bathroom are located on the second floor so more stairs. There is a lot of storage for your stuff. Two surfboards, two beach chairs and beach towels were provided. Coffee and sugar are provided as well.
No parties are allowed otherwise you will be asked to leave immediately and your deposit forfeited.
Overall I felt very comfortable at this AirBnB and would stay there again if I wished to be in the downtown area; I feel like it provided good value for money when compared against other downtown hotels. There are homeless folks in the area but that's true of all major CA cities. The AirBnB is in a gated community.
