Location, location! You cannot go wrong if you are on a budget. If you want a place to lay your head, charge up your tech devices and be right in the middle of an exciting part of BA. Great transportation hub...subway, bus, and plenty of taxis. I did a lot of walking. I used the microwave and refrigerator for snacks. You could prepare more I suppose, but
used the nearby grocery store, and bought simple things...yogurt, cheese, ham, bread, fruit, snacks.
Also packed some favorite, simple things from home...coffee, tea, sugar, spices. You can always go out to the many fast foods places, very, very close.
Many of my tours...tango, estancia and cooking supplied excellent meals.
Felt very safe. The police have a high profile here, even an interesting sub station, just down the street.
To be fair, the price is low, do not expect luxury. I would have paid more for more amenities, but I needed the wonderful location. Peka stays in touch, and was very helpful! Gracias.
