Wonderful amenities and location. We loved being just a few minutes south of Mala Strana and not in the very heart of the old town which can be a little crowded. The old town, new town, Mala Strana, the castle, the parks are all within comfortable walking distance.
We loved Artic Bakehouse for breakfast.
The various tram lines right in front of the building -- though we couldn't hear them -- are also very practical.
