The rental price will vary depending on many factors and some people might have found different deals, from experience I would say:
Fully furnished, one bedroom apartment, relatively nice located from 1500/1700 (very lucky/ market price) to whatever you are willing to pay, but as I said, depending on many factors.
You can actually find some tiny one bedroom apartments from 1000RMB if you know where to look, you can also rent out whole 3 bedrooms apartments in old communities for 1800 RMB, will also have to do with your ability to communicate in Chinese, and be at the right place at the right time as these opportunities are fewer.
The place looks nice, the flavour is far from a Chinese bakery shop, it tasted very close to a real french patisserie, I had the chocolate bread and while the flavour was good, it was a bit dry, it did not taste so fresh, so for 10/12 Kuai I expected a bit better, not disappointed but not surprised.
The prices of some small cakes are a bit overpriced too.
Good bakery, hopefully the keep the prices and don't go crazy like some bakeries in Kunming asking 50 Kuai for a one bite cake.
Tried the Pizza here and it was delicious and authentic Italian Pizza, but if you are looking for a more American Style Pizza then Cantina might disappoint you, don't expect to have 1kg beef on your beef Pizza, top 3 BEST PIZZA places in Kunming.
