Great place, great location! Plenty of room, and it is relatively quiet for Mexico City and private. The doormen at the front are very courteous and helpful and the host is responsive to any issues. No hassles checking in, the elevator opens right into your flat which is really cool! Close walk to the shopping and beautiful neighbourhoods and parks in Polanco, not to mention Bosque Chapultepec. We had business to take care of in Polanco nearby and it was a perfect fit for our purposes.
Oh there's a really good, tiny and quite legit Italian restaurant just around the corner on Lamartine. Nice surprise--we went there quite a bit!
