Mikhail you have a great flat nice and clean and with two bathrooms that is a win
we appreciate that you have teething problems with the flat but you have to understand visitors want to get in and out with no problems
cover up the pipes with box around the boiler in bathroom it will look better
get shutters or curtains in bathroom to provide privacy otherwise a person across the street can see you having shower
also on check in welcome people
anyway best of luck you will do well get good people to provide you back up
