First and foremost, Richard is a great host. If I had any questions, he responded very quickly and would check back in to make sure myself and other guests had everything we needed.
The apartment itself is very nice and perfect for guests who aren't planning on preparing big meals as the kitchen is fairly small and there is a mini fridge. This was no problem for myself and my friends who stayed there since we ate out for pretty much every meal!
As far as the neighborhood goes, I mean. Look. I've lived in several US cities (including Downtown LA) and it's fine. I never felt unsafe. Finding parking was not as hard as other reviewers have stated here. Just don't walk under the freeways by yourself. Basically, don't be stupid and you'll be fine!
There are plenty of great places nearby. The Lumpia Company is a great spot (co-owned by Oakland legend E-40!) and Two Pitchers Brewing Company is right across the street and has a spacious beer garden.
Bottom line, if you are staying in Oakland and need a nice, safe, and inexpensive place to crash while you're off exploring the rest of Oakland and SF, then Richard's place is a GREAT option!
