The studio is well placed in La Condesa (and downstair there's a lovely coffee shop with wifi).
The place itself is nice and the patio is a must.
As said in previous reviews, the stairs are steep, which was not a problem for us. And the wifi is on and off.
We didn't see the host but she was really reactive and there is a usefull house manual (with tips and advices about the neighborhood) in the studio.
