thank your for your review, but I just want to make the situation clear. AC works in 2 upsrairs bedroom, in the 1st there is stronger air flow and in 2nd a bit weaker, as you told us, it's not cold enough for you, we brang you several fans to make it better. In Prague it's very unique, that apartment in the city center has an AC, since it's mostly forbidden because of the UNESCO heritage and facade look, so AC is installed in our apartment, where it's possible (on the roof of the building) and keep the rooms located on the sunny side as cold as possible. We had no complaints from our previous guest regarding the sofa bed, but thank you for a notice, we'll check it, of course. I understand, that situation with the AC and tempreture level might be different in your country and you used to different conditions, but that, how it works in Prague, we would love to to install AC in every room to make our guests happy, but unfortunatelly, there is a strickt law, which all Prague citizens should follow.
I hope you still enjoyed our beatiful city!
