The location of this place is absolutely brilliant. The underground station Namesti Miru (Line A) is just a 3-mins walk away. Its easily reachable from the airport by public transport - 15 mins ride by bus no. 119 to Nádraží Veleslavín and then changing to metro line A for another 8 stations (approx 15 mins) to Namesti Miru. The old town and all other relevant spots in the city are easily reachable either by foot or by public transport.
The apartment is located in a nice residential area. I didn't meet Jaroslav in person but he was super prompt in replying to my messages through AirBnB. The self check-in was smooth, the apartment was clean, and the room is facing the courtyard, which made it extremely quiet, despite the fact that the building is on a busy street. There was a minor snag with the wifi during my 1st day, but Jaroslav took care of that pretty quickly. Overall, I had a very pleasant stay and would totally recommend this place to other travelers.
