This space is really quite remarkable, spread over three floors with incredible views of the city. The rooftop terrace is especially wonderful, and we spent most mornings just lounging outside before starting our day. Location is excellent, right next to the park and steps away from the best bits of Condesa.
Some downsides, though: as other reviewers have noted, there is quite a bit of noise from the highway next door, and there is indeed an unpleasant smell in one of the bedrooms on the top floor that seems to come and go. (Our group wasn't too bothered by the noise, but some of us had trouble sleeping with the smell.) Hot water was a bit difficult, too; we only managed to get it consistently from the shower on the top floor, so we all just showered up there.
The place could use a bit of love (a few items, e.g. chairs and coffee machine, were broken), but nearly all was forgiven when taking in the view!
