This is a fantastic place to stay! Juan is a kind, gracious host. The location is very convenient: very close to the subway and bus lines, near some cool restaurants, and pretty quiet. The room itself is cozy and you'll have ample room for storage of clothes so it's great for a longer stay.
The one downside is that the room gets very cold when the outside temperature dips below around 50 degrees, and the space heater provided does a great job but the air gets extremely dry, so a humidifier may be necessary if you're sensitive to that. Not Juan's fault, of course, and he is generous enough to keep you well supplied with bottled water (and a mini-fridge!)
