A great apartment located in Praha 6, not walking-distance close to the touristic city center (which was great IMO), but thanks to Prague's excellent transportation system, only 10-15 minutes away on tram from Mala Strana or Stare Mesto when you need it. There's a very good supermarket (Kaufland) in a 5 minutes walk and a few nice places in the neighbourhood.
We stayed with a 3-year-old kid, and Martina was really gracious to leave the toys of her adorable son for us to play. There are much more toys than in the photos!
The apartment in whole is really well-planned, a lot of great-looking modern art and a mix or vintage/modern furniture! A sizeable library in Czech, French in English if you're interested in art.
Martina was quick to organize the check-in and set up the whole process!
Overall, a great place to stay in Prague, especially if you're a family or need a little break from the madness of the city center. Would definitely stay there again.
