Pros:
This place is in a perfect tourist location. It's right in the centre of Prague with all the amenities you need right outside your door. Despite the busy location the apartment is very quiet, and it's perfectly clean and spacious.
Cons:
No curtains or blinds in the master bedroom or ensuite, and with neighbour's windows directly opposite these rooms, people would easily be able to peer into the apartment, which may be pretty uncomfortable, unless you're an exhibitionist. Additionally, in spite of the really comprehensive directions from the owners, which was very considerate of them, it was a struggle to actually find the apartment in the beginning.
Conclusion:
Don't think it's value for money, since there are numerous cheaper places in Prague with more private apartments in roughly the same location.
