My wife and I stayed in Jan's place for 4 nights and were really pleased with it.
The apartment itself was spotlessly clean and very well equipped. It was cold and snowing outside, but lovely and warm inside. The bed was very comfortable. The shower was great.
We enjoyed eating out as there were great vegetarian restaurants, so didn't use the cooking facilities in the apartment, but it looked well equipped.
The apartment is in a quiet street. Certainly with the windows closed it was very quiet. Too cold to sit on the balcony, but there is a nice view from there.
Jan left vouchers for breakfast at a nice restaurant which was just around the corner. This was a great start to the day. There is a tram stop just outside the restaurant which was handy. To save the hassle of looking where to buy tram tickets, Jan had some in the flat available for purchase, which was really handy. The tram is a great way to get around, although the apartment is only about 20 minutes walk from the old town, some of that along the river.
Prague itself was amazing. We arrived on January 6th, the last day of the Christmas markets, which was nice.
Jan was very helpful with tips about where to go and eat etc. He also answered any questions very quickly and helpfully.
I would definitely recommend staying in Jan's place 😀
