The unit was a great value for the price, and I would definitely stay there again.
What was great: I met Isabel upon my arrival, and she was friendly and welcoming (as was her pup!), and she accommodated my last-minute booking. Her instructions were helpful, and she was responsive. The unit was incredibly clean and decorated an adorable warm-boutique vibe. The bed was quite comfortable, though I think the unit could benefit from a double bed.
Reasons for 4 stars instead of 5: As other reviews have mentioned, you can hear conversations through the back/shared wall. The unit was quite chilly (Jan in San Diego; space heater was provided), and the shower water did not stay hot for very long. There were also requests to refrain from showering after 10p and more guest responsibilities than other AirBnB (wipe down the shower and tiles after each shower; take out trash daily, etc.).
