First I will respond to being cold.
There is a heater to put on during the early am and late night when chilly.
I pointed it out to them.
There are wool blankets and an electric blanket to stay cozy when sleeping.
San Miguel is semi arid and a very dusty place in the dry season.
The apt. was completely cleaned before arrival.
As far as the theft of items form the car.The first thing I said to them was not to leave a single thing in the car. They apparently did not follow my advice.There have been break ins to cars all over town if someone leaves something in clear view. It was also a very big holiday.
It is a 2 block flat walk on a well lit street to the bus and taxi.
It is a residential street.I consider that an advantage as there is not a lot of traffic on the street in front of the house.
I am a single woman,living in this location here for 7 years and had never had a problem. walking on this street to the bus day or night.
