I stayed in the TV tower apartment for a week in August and found it to be perfect for my needs. The description and photographs are accurate, and in fact the photos perhaps do not do the space justice - with high ceilings throughout it feels spacious and airy. All the essentials were excellent - a large comfy bed, a tiled shower room with plenty of hot water, and fast wi-fi.
The Zizkov area itself is charming and bohemian, with plenty of decent bars, cafes and restaurants within a short walk. Trams running every five minutes into central Prague are a two minute walk from the door, and a metro station is also close by.
Dennis, the owner speaks excellent English and is friendly and personable. He was kind enough to show me around the area when I arrived, and I felt like he put in a lot of effort to ensure I enjoyed my stay. As mentioned by previous reviewers there is a damage deposit (100 euros), which was returned to me in full on the day I left by Dennis and his wife.
Overall, I found the apartment to be fantastic value, comfortable and well-located. If I were to visit Prague again in future I would certainly rebook.More
