Hermann's got 7 or 8 newly renovated, very nicely decorated flats about a 5-10 minute walk from the Angel monument on the Reforma. He also lives on the top floor and is always available to give you some tips on what to see and do, as well as how best to get around, which is helpful in a city this large. The place is a perfect mix of central location with a safe, easy-going neighborhood feel. Possibly thanks to the proximity to the US embassy, there is a big, upmarket restaurant scene on Rio Lerma, which is about 3 blocks away, that was not mentioned in any guidebook I had. Plenty of great street food or less expensive taco joints if you're not into the fancy stuff (El Caminero on Rio Lerma, here for nigh on 30 years, was by far the best). Insurgentes metro is about a 15 minute walk south through Zona Rosa.

Really enjoyed my stay (9 nights) and highly recommend staying here. 5 stars all around!
