I'll go...
First rental was at uni. Everything got repaired on time but the guy was creepy and made sexualised remarks towards me and the three other girls I live with. Was decent with the house, but utter weirdo.
Second rental was let to me for 6 months then decided he wanted to sell so was kicked out pretty pronto.
Third was a studio let out by a lovely woman who used to bring me fresh fruit.
Then lived as a lodger with a woman in her 40s, I was in my 20s. Was brilliant and we had such a laugh.
Then rented another place with a boyfriend. Landlord was decent. Actually lowered the rent when market rates dropped.
Then I rented a place on my own. Gorgeous place. Never met the landlord but I paid my rent, lived in the property. And left after two years. No issues at all.
Next place was a nightmare. Flickering lights deemed a fire hazard by an electrician. He refused to fix Then put my rent up from 850 to 1300 after 6 months so I left. Housing association were great though and took him off their books and refused to let him let through them again.
Current landlord is fab. Kept my rent low. Only gone up £20 a year. Fixed my broken boiler within 6 hours. Let me paint. Sends a Christmas card.
Generally, some bad but mostly ol or good experiences!
