The apartment is just as described (though it feels a bit dark in the kitchen as this part doesn’t have windows, so we had to turn on the lights by day). It is nicely located (litterally in the middle of Prague) so you can go everywhere walking. Many restaurants and markets are not far from the apartment.
Vincent was very helpful, he gave interesting tips and provided everything we needed.
To conclude, this is a good place to stay if you want to visit Prague, don’t hesitate!
