The Hideaway is in a beautiful neighborhood, literally minutes from Balboa Park and next door to a walking trail that leads to a park. The space is well appointed and very, very clean. Spotless, I would say. The french press is a nice touch if you're a caffeine addict like me.
The patio is very nice -- it overlooks the golf course -- but not quite "private." The door to the main house is a few feet away, so you're pretty aware of the occupants of the main house. It's very quiet at night, but there is a fair amount of noise -- doors opening and closing, footsteps on the stairs, etc. -- during the day. Not a big deal for us, as we were mostly out during daylight hours. Still, we did notice it.
The bed was comfortable with nice linens and a TV with ample streaming options. Wifi was easy to use but a little sluggish. Temperatures during our stay (November) were around 70 during the day and mid-50s at night, which was about as warm as you would want it to be without A/C. Turn the fan on and open the windows as soon as you get there.
If you're planning on being busy during the day, and are looking for a nice studio apartment to crash in at night, The Hideaway is a great option. The nearby neighborhood is hip and trendy as well!
