Mirko is a wonderful host. We arrived a bit early and he texted me photos and history of the National Museum to look at and read while we were waiting. Very nice.
Mirko answered all my questions very quickly and really kept in touch with me prior to check in and when we checked out to make sure everything went okay. He made himself available by text for anything we need the stay as well.
The location is perfect! You are only 1 minute from Wenceslas Square so in the middle of New Town. Old Town is 15-20 minute walk as well. I would definitely stay here again.
