Great location, very clean but not a place to hang out in. Perfect for sleeping only, comfortable bed even though neighbours were noisy (we stayed around new year's). Hot water was a big issue. We were only able to take 4-5 minute showers, really fast before water turned cold. Host was notified and she said it wasn't normal and was gonna ask someone to come check it out but we were not available and didn't want to stay in appartement waiting for them (see reason above). Paola was very nice and responsive and hate to leave a 4-star review but also feel that we need to be honest about the stay.
One last thing and this may be normal in Mexico Centro area, there was a small smell of sewers in the appartment that was more prominent in the AM when we woke up. Gotta say that was a bit of a turn off for the Centro histórico área but didn't expect to also smell it a little in the appartment.
