Looking For A Short Term Apartment In Chiang Mia

I am a retired professional and I would like to spend part of the year in Thailand. I have been to Thailand three times, but I have not found my "spot" (Southern Thailand is just too hot for me), so I am looking at Chiang Mai.

I have done some research, and I think the right area for me is West of Old Town, out to Chiang Mai University. I am looking for a place that rents by the week or month, until I get familiar with it, then maybe longer.

My requests are:

1. Must have a pool, kitchen, and a gym.

2. Location is very important. I love to cook and need to be close to markets. I don't like having to take a taxi to go grocery shopping.

3. I am alone, so size is not that important, but probably over 40 square meters.

4. My budget is around 5,000 baht per week or 20,000 baht on a month to month, give or take a few baht. Mostly during October to April.

If anyone has a few recommendations, I would love to hear them. Feel free to PM me.

I will be staying at a hotel until I find the right place.

Cheers.
