Wow, what a great place, and host! I love going to San Francisco, and I would never consider staying somewhere else without checking with Tomasz first. He went out of his way to make sure I had everything I needed. The apt is new, high-end, nicely furnished in modern style. Very comfortable. The building is beautiful and has 24 hr security. Even though in the middle of the city, it is very quiet.
It is located walking distance from downtown destinations, and public transit. I couldn't have been happier.
