This is a great flat - quiet, comfortable and well equipped, and everything is brand new. It has good shops and plenty of food options nearby and is easily walkable from the town centre. Although with Prague's fantastically efficient and cheap public transport, you'll probably just end up getting trams and metros everywhere.
Monika was a great host. She made sure the flat was stocked with basics before we arrived (even emailed me to check for special requests) and when I accidentally shorted out her electricity (whoops!) she didn't make me feel bad - she just came over and fixed it.
