This place is even more spectacular than the photos suggest. The living room is over 40 feet long and the picture window overlooking Prague and the Prague Castle is about 12 feet high and about 16 feet wide. There is also a Samsung 65" Hi-definition TV. The master bedroom is so big I didn't notice the couch (fronted by a coffee table and two antique chairs) for a couple of days. The other bedroom is almost as big and has its own fireplace. The amenities are quite good with a full-size refrigerator, a cooktop, microwave, dishwasher, and a small washing machine. Note that there is no oven.
The location is great, just around the corner from Wenceslas Square and the Mustek metro station and down the street from a major tram station where you can take tram 22 to the Castle and the funicular. There's a large Albert grocery store almost directly under the apartment and another one in the Mustek metro station.
People over 70 can ride all forms of public transportation in Prague for free (including the funicular). All you need is a passport or other photo ID showing your age. We used a US Driver's license successfully the only time we were asked to show tickets.
Jerry is a very interesting guy and a fabulous host. His recommendations were spot on. I particularly recommend the Cafe Savoy across the bridge. The caramel cream-puff desert changed my life. The pizza place right outside the apartment's door has excellent pizza and pasta and fairly friendly staff by Prague standards. They speak good English and take credit and debit cards.
I highly recommend that you have Jerry arrange his driver to transport you to and from the airport. It's currently 500 Koruna (between $20 and $25 USD) and probably less expensive than the notorious Prague taxi drivers would charge. Mr. Marinko met us when we got off the plane holding a sign with our name on it and took us all the way to the apartment elevator.
One word of warning (nothing to do with Jerry or his apartment): we got somewhat fleeced in the town square buying food. The food stand advertised ham for 99 Ck and cabbage and potatoes for 49 Ck. We ordered them, an 89 Ck sausage, and a couple of 60 Ck beers and were charged 970 Ck. The prices on the ham and cabbage were by weight. We thought they were just being generous with the cabbage, but it cost us about $20 US instead of the expected. $2.50. We didn't have this trouble anywhere else.
