Great location for those using the train. I was driving a rental car, found a spot not too far away (about a half a block). There were some delightful pastry shops nearby.
Neighborhood seemed a bit dodgy when I drove in, but everyone was very nice and helpful, even though I spoke no Spanish.
The 4 flights of stairs weren't a surprise from other reviews.
It is a great option for money conscious travelers who aren't daunted by an urban environment. I would stay there again.
