Olmo is a terrific host -- a very sweet guy with lots of good suggestions about places to visit and how to get around via the metro which is right in front of this 9 story modern apartment building. You are at the edge of the Centro Historico here. The Balderas metro and the Balderas metro-bus stops are just steps from the entry to the building, so one can arrive at the Alameda park in less than 5 minutes, and be at the Zocalo via metro in less than 15 minutes. The Ciudadela center of folkcraft is also just a short walk from the building. The private room -- 4th floor -- looks out on the street to tall buildings in the distance, and beyond those to the mountains. The building is almost at the corner of two major streets so there is some traffic noise, including the occasional ambulance or police car siren as they pass by below, but during the night it is relatively quiet for being in the center of this vast city. Lots of restaurants nearby as well as one of the city's most famous public markets, the Mercado de San Juan. Olmo was away from the apartment most of the time I was there and the guest has the use of the modern kitchen, TV, etc., in addition to the private room and bath. There is security at the entrance 24 hours a day . If you want to be in a busy area with easy, quick access to the historic center, I recommend Olmo's place.
