We rented the mansion to allow our families (16 people in total) to stay the night before and the night of our wedding in Berkeley. We wanted everyone to meet beforehand and the couches and kitchen in the house allowed for plenty of room to spread out and enjoy each other's company before everyone retired to their rooms, which were nicely set up.

On the day of the wedding we made arrangements with E.J. so that the vendors and later the wedding party could meet there and do photos at the mansion. The hair and makeup gals came in earlier in the morning, and myself and my bridal party got ready in one of the bedrooms. My now husband and I later did our first look in front of the stained glass windows in a door on the main floor, and we did some family and group photos inside as well (there is TONS of natural light on the main floor). We're really happy with what we've seen so far.

We had family from the age of 4 to 87 and they all enjoyed their time there.

As far as some of the rooms:
The bathroom in the master with the twin bed room attached has its own water heater (not sure about the others) so that was a nice perk, as I take long showers!
That is the same room we got ready in and there was a lot of good light for our hair and makeup gals to use in the morning. It got warmer towards noon (it was in the low 80s that day) but not completely unmanageable with a fan.
My uncle used the kitchen to cook breakfast on the big day, it's a great kitchen, I wish I had had time to use it myself!
There is parking available on the property up a bit of a steep driveway, helpful for loading in and out of the house.
