First and foremost, DONT WASTE YOUR TIME AND BOOK THIS GEM ASAP! Everything about it is marvelous! The decor, location, price, and the owners. Located just 5 or less minutes from the main square, public transport, and handfuls of stores (for food, liquor, beer, and souveniers). The customer service team is very experienced and have obviously hosted their share of guests-instructions are clear as ever to find keys and get in the home. We had enough towels and there was even soap near the sinks and in the showers. The bedding was very lovely and the beds were comfortable. We lived lavishly in Praha for our stay and I bet you will too if you book now. ***
The only issue we came across was noise control. My family and I are not loud people but we had neighbors complaining about how loud we were when we were having dinner at the table at 11pm. Since the building is very old (remodeled of course), the walls are very thin. If you are planning to party hard at the apartment, just do so between the hours of 9 am and 10 pm. Then, take things outside.. Prague has an excellent night scene for that! Just beware of the hefty fee you may get for being too loud.
