This apartment was absolutely fantastic, probably the best Airbnb experience we have had. It is incredibly spacious, spotlessly clean and completely modern with everything you could possibly need - dishwasher, washing machine, tons of maps and info on Prague, even speakers set into the walls (including in the bathroom!)
The location was also fabulous - only a few minutes away from Old Town but removed enough that it was quiet and calm. Even better, it's super easy to reach whether you come from the airport (we took a shuttle that dropped us about a 5-7 minute walk away) or the train station (we caught a morning train and we could walk to the main station within 5 minutes).
If you've got this on your short list, stop debating and just book it! You won't regret it.
