bertha and kazu's apt is beautiful and in the best location possible- in beautiful roma with all the good eats, close to condesa and metro and metrobus to anywhere in the city. The apt is huge with lots of sunlight and plants and a treehouse feel with all the trees outside teh window. Bertha was proactively communicative about things I needed to know and always responded to me within 15 minutes. She and her sister were also very flexible about last minute changes to checkout time which I really appreciate. The apt has the best and hottest shower in mexico i think! :D Unfortunately None of us could sleep well all week. the beds were all very uncomfortable and there is lots of street noise and neighbors having parties or playing the piano in the middle of the night or yapping dogs in the building (till 2am or 6am and then early again in the morning). Just wanted to mention for others who only need a space for sleeping during your stay.
