my husband and I (and our 9 month old) will be in San Francisco early May. We booked a vacation rental (so we could have a seperate bedroom, kitchen, etc. - and good price). It is in Potrero Hill (22nd ave.). I am just a bit nervous now after reading a few posts about Potrero Hill saying it is not convenient to go to touristy places by public transportation...Is it really the case? The place is booked and paid so i'm a bit nervous...Any advice/opinion would be greatly appreciated!
