The flat was disaster - our worst flat ever!! Indeed decorated as a modern art place, but long long ago. So really this flat-museum's shape started to decline probably back in mid 90s. Since then it fall down to a terrible shape, for example: not only the shower holder is broken but the whole system works via boiler (!!), and not the big one - so by the time we managed to switch from tap to shower (not easy in a flat-museum) the hot water has literally finished!! Perhaps, in theory, it might be enough for 1 person, but I cannot see ANY couple having shower earlier than 6 hours one after another!! The only good thing about this flat is location - so anyone who feels OK to spend few nights in archaeological museum without shower - should probably like this place.
PS it was damn cold in there (especially if you travel with little kids), but it is getting warmer these days, spring is coming... besides, there is a nice piece of ancient AC/heater.
