This studio makes the most out what it is.
There is a working mini-fridge, microwave, and toaster along with utensils for quick meals. There is no AC control from the studio, but the fan works fine since SF weather is already cold. The bed is low to the ground and the pillows have no support whatsoever, but it gets the job done and also good for your back. The restroom was obviously recently renovated, so you can expect good water pressure and spacious sink space. One thing to note is that the ceiling is thin, which means you can hear the main house above semi-easily.
Location-wise, it's about a 5$/15min Lyft ride to the nearest BART station (fruitvale) and from fruitvale to SF is about 4 stops/30min ride. This is convenient and the neighborhood is safe within a 5 mile vicinity.
Overall, my boyfriend and I had a good stay and experience. We would recommend this place to our friends!
