Very nice and large apartment in a great location. Would recommend it to anyone staying in Prague.
Checkin not ideal and it's with a hotel 15 mins from the apartment, so make sure you have a bit of time for that. The apartment itself is well worth the extra time spent on checkin.
The apartment is fully equipped with anything you might need (incl a washing machine), beds are a bit soft and it's decently clean. The size and location of the apartment are major upsides.
