First of all, LOCATION LOCATION LOCATION!!!
We've been using Airbnb flats for a few trips we had around Europe, but this flat had the best location! right off the Old town square - close enough to everything but quite enough for a perfect stay.
Second, the flat was very clean, cozy and warm, and had everything you can only imagine and even more.
Anna was very useful and helped with any question we had.
We loved Prague and Anna & Alena's place just made it even better.
Can't wait to come back :)
