Marta Guest House was perfectly located, just steps from the SIT Bus Shuttle from the airport (with many trips a day) and in a great part of the city. The room was just fine, but here's what was great: WIFI worked perfectly the whole time I was there; you can get a coupon for free breakfast and coffee at a local cafe; there's a coop grocery store right across the street; and the hosts at the front desk are amazingly friendly and helpful and charming. When you stay here, you enter through a private courtyard with a working old fashioned elevator and you feel like a local, not a tourist (even though the Marta Guest House is more like a hotel than a private residence). Try it -- you'll love it.
