Finding a good flat for rent, which can meet all your demands, is not an easy thing in a big city. I faced this problem after entering university when I had to find a place to live. At first, there was a problem with estate agents who posted most of the offers and asked money for their services. On no account [I did want|I did wanted|did I want|did I wanted] to give up and continued looking for a flat to rent from private landlords. Neither classifieds nor noticeboard had any suitable variants for me. So I decided to ask my friends for help and posted a message on my social network pages. [No soon|Not soon|Not sooner|No sooner] had I published the post than I started to get offers. So, in no time I had several appropriate options, which I needed to decide on. Not until I had looked over every flat [did I make|did I made|I did make|did make I] the final decision. I chose a one-room flat not far from the city centre with all the necessary appliances. However, [did I little know|little did I know|little did I knew|little did I known] about some rules I found out about as soon as I signed the lease*. So, [under no circumstance|under none circumstances|under not circumstances|under no circumstances] was I allowed to make noise after 10 p.m. I couldn't have any pets either. And, what's more, I wasn't allowed to invite my friends or organise any parties. [Had I know|Had I knew|Had I known|Had I knows] about the rules beforehand, I would have never chosen to live in this flat.
* Lease — a legal agreement in which you pay money in order to use a building, piece of land, vehicle, etc. for a period.
