Hotel is located not so far from centre due to MHD and available Metro just in front of hotel entrance. Hotel it self quite nice and well equiped.
One thing which is bit let down is there is no bar running later than midnight, also room services ends by 11 p.m. so if you arrive late hungry you are ... Room service ends exactly same time when restaurant = zero advantage, only you need to pay hefty fee for room delivery.
You have option to ask not to clean room / change towels to be bit more eco friendly, only advantage is very small biscuit, but at least something, next time will let room cleaned as it means you get tea and coffe too.
Value is ... this year all hotels went crazy with prices, if i did not have it on last moment and hugelly discounted i would say value is very poor. With discount is quite reasonable in comparision with other options in Prague.
