I rent an upper mid-class standard flat, solo, Warsaw, Poland. The only big drawback is heat. From about April to September room temperature stays at >26 Celsius day and night. This lowers sleep quality at night and comfort at all times. An air conditioner seems to be the best solution, but I don't want to pay full price. How can I ask my landlord to buy it or at least partially fund it? Over email unless advised otherwise.
Landlord - me relation
I've been living here for about 1,5 years. The landlord has multiple flats (a few I think since he still manages them himself) but outsources looking for new tenants to a company. I was negotiating prices with a worker of the company first (got them down by ~10%), then met the landlord to sign documents. This is the only time I met him. The rest of our communication is by emails and SMS and is rare. I got only 2 invoices for utilities so far. Seems like he doesn't want to commit much time to the flat.
In the beginning there was another, even bigger disadvantage of the flat - a bathtub with no curtain for taking shower. I pointed it out and he told me that's not a problem and he will send a handyman to install it. What surprised me was that I had to pay the full costs of materials and work to the handyman. The landlord didn't indicate in any way that I will be the payer.
The flat
It's a "studio" - it has a single very big room with a kitchen part (I wanted exactly that). The only windows are from one side and are doors to a balcony at the same time. The normal door is on the other side, so currently the only way to effectively cool it down is to leave my front and balcony doors open for like a half an hour. Leaving balcony doors open at all times isn't a good option because there's grass on the balcony (bugs) and it's not totally quiet outside. I rarely have direct sunlight so blocking it won't solve the problem.
As for the standard of the flat, it has everything modern. If not for the heat I would be totally satisfied.
I don't know how long I will live there. I think at least half a year but it's very probable that a few years. Still I don't want to pay full price for air conditioning since it's investing in a flat that I don't own.
