This listing is essentially a duplex, where one half of the building is dedicated to visitors and the other half is where the host and family live. This was not clear to us from the listing and there is some sound transfer through the walls. Additionally, this listing is very close to the arrival/departure path from the SD airport so you will hear and see big jets overhead constantly. If you are noise sensitive this may be an issue. There are also several sets of stairs.
Otherwise the place itself is nice and Glen is a very good host. Steps from the bay/ocean and good restaurants/market close by.
