Martin was a great host, although I did not get to meet him in person.
Our communication over messages was always pleasant.
He responded to all our questions promptly, advised us on the local area which helped a great deal.
The place is as described and a great apartment for groups, we had the entire place.
It's very local to Old Town, although tram services operate. We chose to use Uber which was always available and not to costly.
Check-in process was simple, the apartment has everything you would need for a stay.
I can highly recommend this apartment and I'll definitely be staying here again on our next visit to Prague.
