The most common cause of bad sleep in a city flat is not noise. It is light — streetlight through thin curtains, the standby LED on something, and the phone.
The proper fix is a blackout blind screwed into the frame, and in a rented flat that is usually not an option.
Start with what the curtains cannot do
Even good curtains leak at the edges, because they hang in front of the window rather than inside the recess. That gap down each side is where most of the light comes in, and no amount of thicker fabric closes it.
This is why people buy heavier curtains and are disappointed.
The thing that beats darkening the room
A sleep mask does what a blind cannot: it makes it dark at your eyes rather than in the room. Look for a contoured shape over a flat one — a flat mask presses on the eyelids, which is why most people take one off in the night without waking properly. If you sleep on your side and a moulded shape feels bulky, a flat silk one is thinner and cooler against the face, at the cost of letting a little more light in at the nose.
This is the cheapest change on the list and the one people underestimate most.
Find the small lights, because they matter more than you think
A single standby LED is enough to keep a room from being properly dark. Go round the room after midnight and count them: router, TV, charger, extension lead, humidifier.
Cover or unplug what you can. For the rest, position matters more than brightness — a light behind you is far less disruptive than one in your line of sight.
Replace the light you do need
Getting up in the night with the main light on wakes you fully, and getting up with a phone torch does the same thing with extra screen.
A small motion-sensing light at ankle height gives you exactly enough to cross a room and nothing more. Under the bed frame or low on the wall, not at eye level.
The morning is the other half
If the room is genuinely dark, waking up gets harder in winter — you are asking your body to start in the middle of the night.
A light that comes up gradually before the alarm is the counterpart to a dark room, not an alternative to it. Dark to sleep, light to wake.
What we would not buy
Adhesive blackout film. It goes on badly, it is visible from outside, and getting it off a rented window is a deposit conversation.
The rest of the room is in the Bedroom.

Common questions
Why do curtains still let light in even when they are heavy?
Curtains hang in front of the window rather than inside the recess, so they leak at the edges. That gap down each side is where most of the light comes in, and no amount of thicker fabric closes it.
What kind of sleep mask actually works best?
A contoured shape over a flat one — a flat mask presses on the eyelids, which is why people take it off in the night without waking properly. A flat silk mask is thinner and cooler for side sleepers, at the cost of letting a little more light in at the nose.
Do small standby lights in the room really matter?
Yes — a single standby LED is enough to keep a room from being properly dark. Cover or unplug what you can, and for the rest, position matters more than brightness: a light behind you is far less disruptive than one in your line of sight.
