I stayed at Maria's place while attending a conference downtown. I liked the idea of staying in a victorian house instead of a faceless hotel. The location was very convenient (only a short 15 minute walk) from Moscone center. The house is on a quiet street and there are plenty of restaurants/shops within 5 minute radius.
The bed was super comfy, the place is very clean and everything is so well organized.
'Post-It' notes around the house are also quite helpful. I definitely enjoyed my stay and Maria made me feel welcome in her house. She is an amazing host. Five star accommodations for sure.
