Searching for a student house, i found a room in a house five minutes away from the university.е-mailing the girl, who advertised it, i found out that her parents had bought the house for her to live in. i met her and we got on fine, so i decided that i'd take the room. the day we were signing the contract her parents were there explaining that they were nice easy-going people. i was pleasing with wat i saw and heard. having read the contract, i realised that it ran till june. i didn't need the room till that late, so i explained that i'd like to move out in april. i was told this wasn't a problem, and it didn't matter what the contract said. so i happily signed, thought i'd been so lucky to have found a place with such great people. it turned out it wasn't so great. the girl, whose parents bought the house, was very unfriendly, leaving notes around the house and complaining about every little thing. having enough of that, i decided to move out early, but when the landlord heard this news, he wasn't sympathetic. the answer was, "i understand your situation, but you can't move out earlier." confused, i said that he himself told me it would be fine to leave before, but he seemed to have forgotten about our conversation. in the end it was my word against the landlord's.paid the rest of my rent, which was £700,1 moved out totally disgusted. the moral is: check your contracts, get everything written down, don't be impressed by promises and smiles.
