We did not feel comfortable providing so much information outside of the AIRBNB website. Since the flat is manged by MADFLATS we had to register through them via a link (that was not very user-friendly), and we had to provide a credit card number and lots of personal information; furthermore, all communication had to be through WhatsApp and not AIRBNB website. This requirement should be clearly stated on the booking page of the flat. The kitchen lacked basic courtesy condiments (such as salt, coffee, cooking oil, extra toilet paper, or detergent for the washer machine).
The apartment is very well kept and its proximity to the metro station is a HUGE plus, there are countless restaurants and stores very close by, such as Plaza Santa Ana 3 minutes away by foot. Although the apartment is in the center of so many attractions and entertainment the noise level was not a problem. If you visit in the summer you will appreciate the cool A/C in this unit.
