I have stayed in this apartment for 2 weeks by myself. It was an amazing choice! The location is perfect, safe and quiet district, beautiful buildings around. The shop is 6 minutes walking from there, the tram station - 4 minutes (and you can also walk home from the Old Town). The flat is located on the upper first floor, there is a blackout curtain if you need to cover from the neighbours' eyes. The bed is great! I do not think you will cook much, but there is this option - kitchenette is very small, however, it fulfills its functions. The toilet in the separate room doesn't cause much trouble. I rarely saw the neighbours. The place itself is a bit humid, but you can open the windows and it will be fine in a couple of minutes.
Sarka and her family are VERY nice and friendly, they supported the flat with everything, including snacks/umbrella/shampoo. She was very responsive to my messages on Whatsapp. I am happy I chose this place to stay.
