I could keep in touch with her by message, although I couldn't see her in person. When we arrived in Mexico City, it was hard because the weather suddenly got cold. (There is no air-conditioning system in this house.) But her friend brought many blankets. Her house was very close to the subway station and was clean and tidy like a picture. The beds were comfortable as well. To tell the weak points, the hot water in the shower is not immediately hot and the temperature control is difficult. And there is no sound insulation, so the noise from all surrounding rooms is heard throughout the day.
