In terms of utility maximization, given the price and quality ratio, I can say that this apartment is one of the best options in Prague. I do stress the perfect location of this place, which is within walking distance (up to 60 minutes) from the gems of beautiful Prague. I did not use public transport at all.
The host, Anatoli, was helpful as usual. So, I can only fully endorse and recommend this place as a hub for exploring the Prague.
