The house is very clean and spacious. We had 10 people and there was plenty of room for both relaxing and sleeping. The kitchen provides everything you need to cook and bake, and the bathrooms can easily accommodate a large group. We had no problems with wifi either.
To note: this house is part of a duplex so there is no backyard. Other people are living underneath the house, so noise is a real consideration. Footsteps can be pretty clearly heard.
As for location, the neighborhood is on the older side and can be about a 30 minute drive to the UCSD/La Jolla area, but it is conveniently located by Balboa Park and the zoo. It is within walking distance of a good number of small restaurants and bars. Remember to use your parking break on the hills!
The information for this house was sent with ample time ahead of our stay, and Evan responded very promptly to our questions.
Overall a highly affordable and worthwhile place to stay!
