Super clean, secure, and spacious apartment in the middle of everything but still a few blocks off the super crowded bits so it's serene at night. Great art and tons of books make the place homey and welcoming. Mark was punctual and very accommodating - meeting us in person at check in and providing a ton of info on the city. He even provided a place for us to leave our bags our final day after we checked out! If we ever go back to Prague we will see what properties Mark has availabe :) Thanks Mark!
