What a fantastic place to stay - right in the heart of the city, with great restaurants, shops & sights all within a 5-10 min walk in all directions! Apartment is in a quiet & peaceful spot within its own little courtyard so is peaceful despite being so central.
Facilities are great for families (we were a couple with 2 x teenage sons), and host Michael could not have been more helpful - arranging taxis to/from airport and very fast communications throughout - really good example of how an airbnb stay should be!
I highly recommend this apartment as a base for exploring all that this wonderful city has to offer. For example, a 10 min walk would get you to any of the Charles Bridge, the Old Town Square & clock or Wenceslas Square, while a 20 mins walk would get you to the castle & cathedral across the river. We stayed for 3 days and never needed to get a taxi or public transport once as you can reach all the main sights on foot from this apartment.
Tip/suggestion - we found Cafe Louvre on the 1st night just around the corner from the apartment at Narodni 22 - a classic Czech cafe/restaurant with fantastic food in a beautiful 100 yr old setting, washed down with a few Czech beers and a few games of billiards adjacent to the restaurant - made for a great evening.
