1. This letter is about Feng Shui. Don't believe it or not. Generally, small problems of house feng shui can be solved, but you need to explain in detail what is going on there.
2. Regarding the floor, there are good places, convenient places and bad places on the first floor. If there is no moistureproof layer, the first floor usually spends more time on tides than other floors. If there is, don't worry. It's okay. And if it is an elevator room, the first floor will be a little more lively, and people will take the elevator from the first floor.
I can't explain in detail about the apartment type.
Keep asking if you have any questions. I hope it helps you. Congratulations on buying a house. It is not easy to buy a house these days.
