Veronica is an extremely accommodating and communicative host. Was responsive immediately for any reason.
The location was nice. A long way from the 'traditional' tourist spots of Roma & Condesa, but Del Valle Sur has a really relaxed vibe and it's close to Plaza Universidad for shopping. Also close to Coyoacan which is nice for a night out.
The apartment was very eclectic, however it had everything needed to make a comfortable stay. The concerns were the hot water went out a couple of times (it's powered by a flame), the WiFi didn't reliably reach other rooms, and the bathroom sometimes smelt strange (maybe coming through the window?).
I believe the walls are very thick, because it is one of the quietest apartments I have stayed in CDMX. This may be the reason the WiFi is spotty.
Overall it was good value, and Veronica is a great host!
