The Calming Blue Room was a great home base for our adventures in San Francisco. We rented bikes and took full advantage of being close to the Wharf, downtown, and Golden Gate Bridge. The room itself was comfortable and peaceful. We slept well every night and had no issues with bathroom access even though it was shared. There is a low hum that happens in the morning apparently from the diner two floors down, but it didn't bother us.
Speaking of Pat's Diner (downstairs and two doors over), they provided a great breakfast for us more than once.
If you're coming in from out-of-town and you've got luggage, we'd recommend Uber or a taxi. The house is a 30 minute walk from the nearest BART station.
We loved the art and the overall ambience of Elisa's house and would recommend it to anyone looking for an easy, central location for exploring the best of San Francisco.
