We enjoyed our stay in Prague in this appartment. Martina was helpful and arranged that we could pick up the key close by after our late arrival.
The place was clean and cozy. It's perfectly located in the heart of the city with a lot of sights in a walking distance.
Unfortunately the windows do not provide very good noise insulation. Noise of cars and drunk people leaving from bars in the vicinity were rather loud in the apparment even when the windows were closed. Earplugs are recommended for a tight sleep.
