Rudy's first level studio apartment is centrally located in SF. We took many trips from the nearby MUNI historical street cars and subway. We felt safe walking the streets of the popular Castro neighborhood at dark. The streets are clean and transportation is less than 3 blocks away. Highly suggest using the MUNI app and purchasing the 1-day passes each day.
As for the apartment, we couldn't ask for a better place for our 3 night trip. The place was clean and well stocked. The bath towels are the best I've ever used — soft and thick. From the city sights and a clean safe place to rest our heads, we were on cloud 9.
