Jiri's place is at a great location. I recommend it even though this is my first ever 3 star review and I have stayed at several Air BnB's. Jiri is also very nice and communicates well. The morning after my first night, Jiri also sent a message to ask me if the place was "clean". Nobody has ever asked me this. And this is where I had a little problem. Why would he ask this question? Is that because he knew the room provided was anything but clean?
The linens as well as comforter were not usable and so were the pillows. They were clearly not washed and the comforter inside the cover was in shambles. It was provided for two people but not even one can wear it.
When Jiri asked if I was happy, I said yes, because I didn't believe he would do anything to fix it. How can someone provide something like this to begin with. I didn't think he would do anything meaningful to fix it.
Also, the bathroom has a drainage problem. The water clogs while you are taking shower (I shutdown water frequently while taking shower and yet). When you shutoff water, you can still see the water pretty much on top of drainage hole. This causes smell. Close the bathroom door when you leave, then its not a big problem. Totally ignorable if beds were clean.
This is still a great apartment. I'd still recommend it if you are going to Prague. It will be hard for you to find a location as good as this. But if you choose this place, I highly recommend you take your quilt covers, linens (and pillows if possible) with you.
