Exactly as described, the apartment was in the heart of Old Town Prague which I think is the apartments biggest asset. We stayed in Room A, a spacious double bedroom on the 3rd floor. There is a communal toilet with a separate bath/shower room, as well as a well equipped kitchen with ample cooking facilities and fridge space. An iron was also provided if required.
There were 2 other rooms in the apartment, both occupied by presumably Air BnB guests, as well as one room for Viola, who was very kind showing us around, providing tips and recommendations on what to do in the city and allowing us to check in early. Although the flat was fully occupied, toilet/bathroom use was no issue.
The apartment itself is opposite a police station which was reassuring, although we found Prague as a city to be very safe during our stay. It is a very walk-able City, so we really did not rely on public transport at all during our stay given the ideal location of the flat, although if you did want to use the public transport it works out at around £1-2 a go depending on how long you buy a ticket for.
Overall the flat was as we expected it to be for the price and we had a great time in Prague. Thank you to Vincent and Viola for your hospitality and regular communication throughout. We would definitely return if visiting for another short stay.
