David’s place is very well located in Ve Smeckach street.
It is accessible from the airport by bus # 119 to Metro Nádraží Velestavin. Then only 4 stops to Muzeum station which is only 5 minutes walking distance to David’s place.
There is an elevator in Metro, so if you have a heavy suitcase( like I had) you will appreciate it!
You can walk everywhere from that location!
Grocery store on the street, but better price is in a big Grocery store ; Albert, or Billa
Prague is a great place to visit!
