My advice is: bring a good toolbox with you. To say it is outdated is to say nothing. Not easy to decide from what point to start ... Well, maybe:
1) Bathroom on the ground floor. The lock just falling down, literally to your hand. Lucky I have a screwdrivers set in the car, we've fixed it
2) Bathroom upstairs. The locker work 8/10 times like russian roulette. My niece, a little girl, been locked here and she was really scared
3) Anti-insect door screen upstairs. It needs 4 minutes to open it, then 5 minutes to close. Be careful with that
4) Furniture, shower supplies etc. Everything is from 60's and be sure you wouldn't fall for nostalgia because I'm afraid that it didn't work even in 60's
5) Belle Property who's managing this house using Security Bond scheme that looks like a scam
