David was great to communicate with - he answered promptly at all times, and also was very understanding when our plane was delayed. We were attending a conference at the Prague Congress Centre and this was very convenient to the apartment. The apartment is very practical and the description is accurate. It is not the most homely apartment but was perfect for our trip and very large. Many thanks David.
On a completely separate note, we were completely ripped off by a taxi from the airport - it appeared an official taxi, with a sign and meter, but charged us x 3 times the usual rate. My understanding is that a taxi should cost 500-700, so be careful and agree the rate prior to getting in, or else use Uber!
