Anna is a great host - she explained the easiest way to get to the flat, was available late at night to welcome me and even lent me an adapter when I explained I had just lost mine, which was very kind.
The flat itself is bright and cosy and should meet all your basic needs at a very reasonable price. It's in an excellent location for access to central Prague and from the nearby Florenc station you can easily get anywhere in the city (including the central station).
I enjoyed my stay here and will happily return if I visit Prague again in future.
