It can't be calculated by square. A facade house is 3.425m wide and 1 1 m long, but there are stairs behind it, and the actual facade area is less than 30m2. The current annual rent for a room like this is 30 thousand to 35 thousand, which will be a little different according to the location. If you are looking for a 100 square meter apartment, it doesn't look so big at present. The big one is that the two rooms are connected together, and the rent is 60,000 to 70,000. At present, no one has three rooms connected together, so it is unrealistic for you to find an apartment of 100 square meter.
