Stately old mansion, a 20-minute walk from Plaza de Armas, with comfortable rooms, good breakfast,…read moreand a very courteous staff. Reviews on other sites complain of "no A/C", but our room, on the 3rd floor, was fully air conditioned. (My one tip, though, would be to try for a room on the 2nd floor -- because there is no lift -- and after a day of walking around town, especially in the summer heat, that 2nd flight of stairs is brutal.) There is also free parking behind a locked gate, if you have a car.
At first glance, the neighborhood seems a bit run-down and questionable, what with the double-gate security and all, but walk around the corner behind the hotel and you're in the Barrio de Brasil, a great neighborhood with families at play in the park, and a lively restaurant and bar scene. A block the other way are 2 great, quirky restaurants, Ocean Pacific and Los Vikingos (see my separate reviews of both).
So, while you're not right downtown, you're a short walk away (or a short cab or Uber ride -- both are readily available), and there's no particular advantage in staying in Providencia or Bella Vista anyway, especially if you have a car. And if you're planning day trips to the wineries or ski areas or Valparaiso or Isla Negra (since there's not much to keep you in Santiago), you're a couple of blocks from the highway, which makes getting out of town much faster and less aggravating.
In all, a good choice at a reasonable price. Recommended.
