We didn't see Paul but he was caring about our stay during all its duration, sending sms and emails to know if everything were ok. We were free to contact him if needed but his friend Marketa already gave us some really good advices about the city. We even had some wine and chocolate! Thank you very much!
Everything was already clean when we arrived, we have nothing to say about it, perfect.
The flat is pretty central so we weren't far from old town and didn't need to take public transportation. For our arrival, it was near the metro so no problem about that.
Only little problem: no wifi but Paul says it's gonna be fixed soon, but it's not his fault.
So, this was a good stay, I recommend Paul's flat! Good continuation :)
