My 2.5 week stay in Calle Isabela de la Catolica #105 was fantastic! The apartment is clean and bright, well-decorated, and a great comfortable space. I appreciated having the patio laundry (only a washing machine, but clothes line-dried quickly/overnight. The apartment is safe and secure – there is a locked entry gate, and a triple-bolted lock on apt door. There also is an elevator. It is a great, central location, with shops and vendors right there, great “al fresco” cafes off of Calle Isabela to the north (towards Zocalo). Lu is a super-responsive host, and she has a flexible pricing scale that allowed me to stay in the apartment the entire 2.5 weeks, increasing the rental fee only when I had visitors. Maria, who came to clean that apartment, is lovely, friendly, and very thorough. The building has a trash/recycling center on the landing halfway down to the entry - very convenient. Yes, this is a central location in the world's largest city, so yes, ther is street noise at night, but each bedroom had either a ceiling or a standing fan to help with both ventilation and night-time noise. You are within an easy walk to the Zocalo, Mercado San Juan (great for produce and other Mexican treats), Palacio Bellas Artes, other sites and conveniences. I so enjoyed my stay in CDMX --- only problem --- it's not enough time! There is so much to do and see, and the city is bustling! I highly recommend this rental option!
