We arrived too early to check in, and Soraya's son, Milan, met us, took our bags and recommended that we have lunch at Chiquita, the café on the ground floor of the apartment building, while we waited to check in. After lunch he brought us the keys, went up with us and oriented us to the apartment and the way things worked. Throughout the week, Soraya always responded immediately to questions and to address any problems that arose.
Two things we particularly appreciated: First, Soraya left two laminated sheets with 1) information on the apartment and the appliances; and 2) recommendations for restaurants and places to go. The second is that she had the pantry stocked with capsules for the coffee machine, and with salt and pepper, sugar and oil and vinegar.
As everyone has said, there could not be a better location. We were down the street from the Plaza Mayor and in a neighborhood that was easy and fun to walk around in. There were several small food markets within a few blocks.
