This is a great apartment. The location is very good - in a quiet, upmarket neighbourhood with shops (5 mins walk to the Albert supermarket on Vinohradská) and restaurants, next to a lovely park. It is less than 10 mins comfortable walk to Jiriho z Podobrade metro station, which is on the A (green) line, so very for travel to and from the airport, Old Town and castle.
The apartment was very clean, and very quiet - we welcomed the stricture to keep quiet after 10pm.
I thoroughly recommend this apartment, and will likely look to stay here again if I return to Prague.
