I had a really pleasant experience at Irazema's place and it surpassed my expectations.
Her apartment is very clean, organized, comfortable, quiet, well located and well equipped with everything you need for a short or long stay.
There are grocery stores, pharmacies, several cafes a couple blocks away and not to mention it is close by some of the best bars and clubs in Mexico City.
Irazema is very polite, respectful and hospitable and was always responsive to help with whatever needed.
Regarding what other reviews mention about noise from a school next door, which was something I was worried about initially, it didn't bother whatsoever.
On top of that her windows isolate extremely well in case you want complete silence at any time of the day.
She's a great host and I definitely recommend to stay at her place and will stay there again in a future opportunity.
