We had a fantastic stay in Prague at Ondrej's place. The flat was clean, fairly spacious with access to a lovely garden. The location was also pretty good, 10 minutes walk to a metro station and there's a tram stop even closer, but as it's downhill quite steeply from the apartment, we preferred using the metro instead. A Lidl by the tramstop made sure we were well stocked with everything.
Ondrej's son (I presume) welcomed us, and showed us everything we needed.
I can only recommend staying here.
