We live on the 5th floor of a block of flats. There are two apartments per floor with a wide and spacious hallway between them.
There is a large underground car park with bike racks.
As the nights got darker, I began to bring my bike up the elevator and park it in the hallway outside our flat.
It is not in anyone's way at all, cannot be seen by anyone except those in our flat, does not block any entrances/exits and does not pose a health and safety risk. The hallway is only used for entering and exiting the front door of the flat and not for spending time in.
The reason I leave my bike there rather than in the car park seems fair: the car parkis very difficult to get in and out on a bike, involves a long twisting ramp designed for cars which is completely blind - it takes a huge amount of energy to get up on a bike and a lot of drivers whiz down it at high speed making it dangerous.
The alternative exit involves four flights of concrete stairs.
The bike racks are also packed with bikes, literally stacked one on top of the other in a heap.
As it gets darker, the car park doesn't feel very safe - there are no cameras and a lot of corners and cubby spaces.
Getting down into the car park, unlocking my bike and getting otvout adds an extra 15 mins onto my commute and is physically exhausting.
The conceroerge has now stuck up signs in our hallway banning bikes being kept outside flats, stating there is plenty of space in the car park.
AIBU to want to keep my bike in the hallway? It honestly isn't impacting anyone's life in anyway and is not an eyesore. We do, however, have a very passive aggressive housemate who has control issues and form for making points via a third party (she called the police on a previous housemate for making noise in the corridor and launched an environmental health investigation against her own flat to make a point about noisy housemate)
