My group was supposed to meet David at the Airbnb at a specified time and he was very gracious when we surpassed that time by 30 minutes due to a late tram and having no wifi to reach him until we got to his location. The room was great for 3 people and a great location to boot. About 2min walk to a tram stop, 5min walk to a subway station, right across the street from the train station (though not noisy), and a 15-20min walk one way to Old Town Square/Charles Bridge, and a 12-15min walk to Wenceslas Square. The place was very clean and was supplied with a coffee machine, microwave, portable burner, and kitchenware. Communication with them was very easy and they responded quickly.
