Rosa's place is fantastic! Very spacious, cozy, and clean. It's quiet at night, and there's a well-working AC (we went in February, it works as a heater, we didn't try the cold mode). The location is 40 min walking from the old Town, not that much if you like walking, anyways the metro station is only 8 min walking from the apartmet, from there, you can go where you want.
Rosa is extremely welcoming and nice, she will provide for everything you need and give you useful advice for your stay
