We really loved our stay here. The house is beautiful! It is very historic but extremely well maintained. The bedrooms and bathrooms were good; the master bath was amazing with a huge walk-in shower area. The dining and living room area are luxuriously large. The dining room has huge windows with a great view out on the city and bay; there is also a small balcony adjacent to enjoy some sunshine outside (table and chairs too). There was a nice big-screen TV and speakers in the living room; perfect for watching the finale of Game of Thrones (however disappointing it ended up being). The key was in a lock box on the porch, which made it easy for our large group to access. This unit is on the ground level with the entry from the street at the top of the hill; as the house is on the top of a hill, there are 3 units below it. We saw a few of the other people as they walked to their homes, but we never heard them or had any disturbances. The area on Banker's Hill is very nice and close to downtown, good restaurants and Balboa Park.
The host Marie also was very welcoming and accommodating. We needed a corkscrew for a wine bottle, and she dropped one off. I also ended up leaving a few dress shirts in the closet (the master closet is huge BTW!); she mailed them out to me in a jiffy! She also had stored some local Stone beers in the fridge for us to enjoy!
Trying to think of any problems or flaws, I really can't think of any. The closest I can is that the stove is fairly dated; however we didn't do any cooking so didn't even need it. The coffee maker and refrigerator both worked great and we definitely made use of those.
I would definitely recommend staying here if you are looking for accommodations for a group!
