Maria's place is an awesome place to stay! She is super nice and the house is very clean. The area is also very close to downtown, though there is a good amount of homeless on the streets. Be careful of going north of Market St., as you'll be in the tenderloin which has a ton of homeless and drugs. Maria is an awesome host though, and was more than helpful allowing me to store my luggage in her garage both before and after my stay. Highly recommend!
