Jiri's place is exceptionally clean and is quite cozy. The phone he adds for metro tickets is actually quite handy as finding metro tickets in Prague can be kind of difficult at times.
The washer machine is a nice addition and the apartment is in a quite and safe part of town.
The distance however is a significant difference than expected. This could have been caused by the metro difficulties we experienced as the main like it town was closed for the month and we were re-routed. This made the commute home 40+ minutes daily.
Lastly the wifi was sadly inconsistent and completely went out our last day and night making finding directions to train station and using web much more difficult.
All in all clean safe place slightly farther from sites than you may expect or want unless you prefer to retreat out of town a little bit.
