Always amazing! But flat have one big problem: you need going down through 5th floor to first 2-3 times an hour, because electricity doesn't work long if you need, for example, wi-fi router, powering smartfon and having bath. Thats all! If you need something more (things that need electricity), all broken and you need going down and after restart sistem going up to apartments. It's really big-big problem! All other is great, recommended!
