Although Petra was away, she and Ceci made me feel welcome and at home from the minute my request to book her studio was made. Before I got to the place, Petra made me aware that I was to be upgraded to the larger apartment free of charge. I thought the studio was already pretty affordable due to the location, but this made it over the top. The actual place is beautiful. Lots of bright light, alot of space in the bedrooms and living room, full kitchen, nice restrooms. There is a terrace balcony with great views of the city. Ceci does a really great job and brings fresh pan dulce and fresh fruit daily. I originally booked the place for 5 nights because I had not realized my flight was until a day later, and it wasn't a problem to request an extra day. There is satellite TV, internet and a computer there, which helped me out alot after I got my phone stolen on the metro. The place is like a mixture between a hotel and someone's family home. There is beautiful art and pottery around (some of it for sale), and alot of guidebooks, maps and helpful printouts for the newbie traveller. The building is an old 6 story building that is a short walk from the Zócalo and very accessible to the metro. There is alot of people walking around but on the sixth floor where the apartment is you get no noise. The only slightly negative thing I can recall, which didn't actually bother me at all but can bother some, is that the hardwood floors creak when you walk on them; understandable because it is an older building from what I gathered.All in all I highly recommend it for its location, cleanliness, hospitality that Ceci and Petra provide and its affordability.
