Yanina and I communicated by email several times leading up to my trip. She always responded promptly and provided excellent information.
The apartment is in a doorman building, in a great neighborhood very close to the green (d?) line puerrydon subte station.
The studio itself is pretty spacious. A living/dining/kitchen area with microwave, refrigerator and 2 burners (like hot plates).
The bed is extremely comfortable and there are extra blankets and pillows if you need them.
Bathroom is nicely sized as well, with a tub/shower combo (no shower curtain, but the half wall blocks much of the spray from hitting the tile floor.
There is a walk-in closet with a decent amount of space, though if you're travelling in tandem for a week, you may have to struggle to find enough storage.
I enjoyed my stay at Yanina's apartment, and should I go to BA again, I would try to rebook.
