I know there is a "Science and Technology Square" at the intersection of Xi 'an Road and huanghe road. There are three hotels on the pedestrian street, just opposite Carrefour (not far from the seafood market, within 5 minutes' walk). One of them is called "Zhu Leyi Inn". The telephone number is 0411-39760001. You can ask first. The price is also very cheap. 20 beds (one room can accommodate 4-5 people), 40-ordinary rooms in 50 yuan, and 80 standard rooms. There is also cable TV and a bathtub, but the room is a little smaller. If there is no requirement, it should satisfy you.
I can't find the business cards of other families. You can ask this first. If the price is ok, you can visit other families. It's better if you live next to you.
I hope you have a good time in Dalian ~ ~
