I've stayed here 4 times now - it's my 'go to' place in Mexico City. The apartment building is incredible - as central as you can get and yet, because of the clever design of the building, extremely quiet and peaceful. Facilities include an acclimatised pool, a very well-equipped gym with personal trainers, a cafe, courtyard seating areas, business centre, even a small cinema apparently.

Pauline and her sister Gaby, who manages it, are flexible, relaxed and welcoming hosts, always on hand to sort out any issues or needs. There is even a foldable bike they are happy for guests to use! (Highly recommended on Sundays when some major roads are closed to traffic in the centre to promote bike use.)

The apartment has everything you need and is well maintained and in good condition. Beds are comfy, showers excellent, etc. In terms of style and feel, it has been kept pretty minimal because they don't live there and perhaps they have a lot of turnover of guests, so I guess my only suggestion to make it go from wonderful to perfect would a little more furniture and furnishings, such as bedside tables, maybe the odd picture, cable TV, to make it feel really feel like "home", as it can feel a little sparse if staying for longer periods. However if you're just there for a few nights and mostly out sightseeing this shouldn't bother you.
