Daniel was very accommodating. His response time was immediate. We requested for slightly earlier check in and also for leaving luggage after checking out. He agreed to it for free. I have the impression that if we request something, Daniel will try his best to accommodate it if possible. The first morning of our stay Daniel even texted us asking whether he could help with anything. I think that was a very thoughtful gesture.
The place is really nice, clean and central. We walk to everywhere. Probably less than 5 mins to the old town square. Some part of the corridor floor creaks everytime we walk though. Have to be careful in the morning not to wake others up when going to the separate but private bathroom. But for us, we didn't hear anything from inside the room.
Internet is very fast. It doesn't work near the window though. So sit on the sofa nearer to the door and you will get very fast Internet.
If I visit Prague I will definitely rent Daniel's place again. :)
