We are couple. We had a really great time in Praha for kindness of Mark. He is very smart and kind host knowing well what guests want so our trip was very comfortable and favorable. Thank you, Mark.
Short stay(2 nights) but happy memories in this flat. It has one bedroom, one kitchen, one bathroom, all wooden floor. It is cosy and clean. Nearby tesco(supermarket), yammy bakery(ground floor), nice restaurant(name; Home Kitchen), old town, charles bridge, everything was good. Most of all, Mark called the cab for us earlly in the morning, it was on time and exact cost no overcharge. So if you have some schedule between praha, don't worry. Asking to Mark, no problem. He is very reliable host.
But a little bit of notice is there are not laundry machine, soap, shampoo, coffee machine(instead Moca port)

I'm willing to recommend this house.
Have a nice trip. God bless you.
