I stayed at Marianne's place for two nights and it was great! She welcomed me in her home and showed me everything. The "unreal" doors were not a problem at all, Marianne has her own tricks with a sound machine etc.
Her place is great if you want to use public transportation. 10 min walk and you are at the bus stop. Super easy to find everything, she has a little book in your room where she explains her rules again. She asked me if she can help me with anything, offered me tea and toast when I arrived. Marianne is a wonderful person and her place is great. Everything as described on her profile. 100% recommended. I hope to visit San Diego again soon and hope to stay with her again!
