Always a pleasure staying at this AirBnB. Have stayed here several times this year on my trips to San Francisco. The location is perfect since you are practically in the heart of The City. The closest Bart station is Powell and it's literally a 5 minute walk. The neighborhood does get noisy at certain times of the day and on a few nights, ear plugs were used.
The WiFi connection is excellent and the hot showers after a long day are a plus. The hot water does take a while to heat up, so be patient. Hiromi is a great host and is always available to handle any situation that arises. Enjoy your stay at this little gem of an AirBnB.
