As you can see even in the heart of Winter it normal high is in the 70's seldom below mid 40's at night. It's a bit lower than say Patzcuaro which can be rather cold.
While I have only been there one week so far, that in early March I found a medium weight sweatshirt was more than adequate early mornings. I'd shed it usually by 10:00 AM

PS I meant Guanajuato is at lower elevation than Patzcuaro so not as cold. I always get a room with a fireplace in Patz but never felt the need in Guanajuato.

Thanks much. I'll be doing some more checking around to see what I can find for rentals. I just didn't know if we need a heat source at that time of year.

I was there in late february and the weather was just about perfect. Mostly sunny, 70 during the day, cooler but not cold at night.

For a first timer I suggest a hotel rather than an apartment. Your hotel people can be very helpful with answering questions, arranging a side trip, etc. In an apartment you are totally on your own.

I liked the Hotel Luna, right on the Jardin. But there is a small hotel tucked into a beighborhood just northeast of the Jardin that might suit your desire for something that feels really local. Is it the Casa Azul?

If your apartment has a good southern exposure, that would help greatly. Otherwise, it can stay cold for a good part of the day. Last year in SMA it got down to 19 F in December, so it can get cool. But that was an exception. But its said that in the winter in this part of Mexico, you wear a sweater indoors but take it off when you go outside.
