Jan is a wonderful person, very friendly, maybe the best person from Prague that I've met! I will recommend this flat just for him.
The flat is pretty old and everything looks like dirty, the bed for my mom and my sister was uncomfortable for my the couch was perfect, but is not so much about the mattresses is more about how clean they are or how often are they changing the furniture in the flat, probably you will think that everything is coming out from a basement and nobody cared enough to make it looking good again. Also the shower is not the best I didn't take a shower there for example because I couldn't but anyway I guess that for the location "it worth".
The location is simple amazing and the Russian restaurant next to the building is just the best (for real) best restaurant in my trip the food is incredible and the prices ..... nearly nothing really really cheap!
I would take this flat again just if I will go to Prague just to make party with my friends or something like that, and normally with young people. My mom was complaining the whole time .. for me was ok!
Thank you so much for everything again Mr. Jan!! I wish you the best!
