My girlfriend and I stayed at Bara@Jirka's place for 6 nights. Bara@Jirka collected us from the airport upon our arrival in Prague. Their place is lovely, very clean, spacious and generously equipped with everything you need. They even provided some snacks and drinks.
It is a 3 minute walk to the closest metro station, even closer for trams, while the place itself is on a quiet street (into the city centre is maybe 15 minutes from Petriny Metro). They also gave us some tips for places to visit during our time in Prague, which was much appreciated. Would absolutely recommend.
