Pros : very good location, near two metro lines, A & C. You may reach any place in Prague without any hassle. Host were polite & would provide you support if required. Good restaurants option available nearby. Wi-Fi was good.
Cons : room is very small with no windows. Without a lift, getting up & down the 5th floor was a task in itself. There's no cot, it's a mattress. Toilet is shared & hence may be a concern for few travellers ( although there were no issues as I was for 2 nights only). No hangars/wardrobe available for keeping your clothes.
Overall, I would say a good choice for a solo budget traveller, who doesn't bother about the cons.
