Overall, highly recommended for short stay.
The host: Good communication. Reply was prompt before the trip. Andrea's mother waited for us at the door to give us a very warm welcome and a quick tour. She even made sure that we know how to open and close the door!
The place: Clean and compact. But feel bad for making the Flat dirty when cooking. Windows must be opened. The bathroom is modern and functional but it lacks of toilet roll holder and bath mat. It is not quiet enough at night, can hear people talking outside and horse carriage passing by. Should prepare rags or paper towels for the kitchen. The kitchen sink get all wet and messy easily. Beware if you have big luggage, it can be a challenge to carry them up a flight of stairs (just about 10-12 steps) after entering the main door.
The location: Great. Few minutes away from the Old Town Square (a lot of bus and walking tour start here) and the pier (for river cruise). Just 2 minutes walk from the famous Paris street for luxury shopping fix. 1 minute away from Intercontinental Praha.
