Margo's place is great! Location is fine (+-20 by bus to the harbor, uber +-$8). The house is very cosy, just don't forget to take your shoes off ;) Margo has a cute dog that walks around the house. We were in the Red room, which was a quiet location in the house but did get a lot of street noise (also from planes flying over), Margo provides ear plugs to help overcome this :). Margo was a great host, very kind and with wonderful hospitality. One thing to keep in mind is the check-in time that is only one hour at the end of the day, otherwise there is a fee of $25 (this is explained in the house rules, I suggest to read them thoroughly).
Overall we had a great stay and looooved San Diego! If you're looking for a comfy, cosy and very hospital place to stay - Margo's place is the best!
