The Castro cottage was a great place for us to stay. Very close to Castro St and public transport. The cottage itself was cosy and there was no noise from the street. The kitchen is large enough to cook a meal and we had friends over for dinner.
San Francisco is -as you know very hilly - but this apartment is easy to access.
Matt was friendly and a great host. He was refurbishing his own house while we were there, but it did not bother us at all.
