Andrea's place is in the perfect location! Across the street from the famous San Telmo market and a few blocks from Plaza Dorrego w/ their tango social dances and performers. Her place should be nicknamed "Hottt Apartment," because the heater in the room works so well and the water is hottt (be careful!). The shower was amazing w/ wonderful pressure. (It's one of those combination toilet/ shower bathrooms). Just be warned that it's quite a hike to the bathroom, down the long hall and through the kitchen. (So if you have a small bladder, you'll be getting quite a workout in).
The room is cozy and it may seem dark at first, but the bedside light is actually quite bright at night. I got a lot of work done because it was just a cozy atmosphere and the work desk helped out.
Andrea respects your privacy and everyone just kind of stays in their own rooms because there are individual TVs. I would have liked to interact more but I was quite busy during my stay.
The only thing that bothered me was the laundry price. Andrea charges 1500 pesos ($6.00 for one load) which is quite expensive, considering the laundromat only charges 300 ($1.50) pesos for one load and my other Air BnB host only charged me 200. (I even had my own soap.) Being a tourist doesn't mean we should be taken advantage of and charged different prices than the locals (one of my major pet peeves).
