Great location, only a few mins walk from shops, underground, the river and the very centre of Prague. Josef is super responsive and helpful, the hotel staff also amazing.
The apartment is very bright and clean, it isn't big but sufficient - I especially appreciated the beautiful bathroom and the comfy bed. The balcony is also a great addition. A bit of a letdown were the thin walls - you could hear everything from the apartment next door, from the other guests cooking, watching TV to flushing the toilet.
