The place looked great. Actually a little bigger than in the photos. With a fridge and a few glasses, cups etc. There is a small, private toilet in the room behind a thin slidedoor. As a couple you should be comfortable with each other but the bathtub more than makes up for it.
The location was close to everywhere we wanted to go. We actually walked the entire city from it. There are nearby cafes offering a nice breakfast and a few restaurants as well. Less than 100m from a supermarket. Oh, and Prague was great. Felt safe and was reasonably clean with very nice people. Had a lot of fun!
