Marilee's apartment is located on the top floor of an old and charming house. The apartment was clean, comfortable, and it has a dazzling view of downtown, the Bay Bridge and the Twin Peaks. To enjoy that view you need to be willing to climb. The street is steep, the walk down to Mission Street is steep and the stairs leading up to the apartment are steep. We did not mind the climb and loved the birds nest view. We also enjoyed the neighborhood. Bernal Heights is quiet and diverse, not a touristy location. There are nice restaurants within walking distance (so long as you don't mind hills) and the Mission and Noe Valley are nearby. Parking was easy during the weekend. On week days street parking requires a permit.
We had one logistic problem during our stay, and our host was responsive in addressing it. I would welcome a return visit.
