This is an outstanding place for a short holiday. The bathroom in particular is super modern and clean. Great apartment, one block away from the main station and all downtown was walkable. Libuse is very communicative and answered all my questions asap. She even was so kind to provide me with a proper desk and work chair upon request.
If you want to stay longer than a holiday you might want to take the following things into consideration:
1) The sun never touches the windows. You'll have lights on all day at home.
2) The internet was unstable. I think most of Prague honestly has unstable internet but if you cannot loose a call or game connection bare it in mind.
3) If you're allergic to either dust mites or mold you might experience an allergic reaction like me. Cant say for sure which of the two broke out. Did not see any obvious mold. It went away the moment I moved out.
4) Cars are parked right next to your bed and living room couch. They change almost daily with people staring at you.
