The apartment was great, really nicely furnished and with absolutely everything we needed. The kitchen and washer/dryer in particular were really appreciated.
The in-person check-in and tour was really useful, and the hosts were on hand before and through our whole stay to give us advice on making the best of our stay - and happily sorted us with cheap taxis from and to the airport.
The location is pretty convenient, just a short tram or nice walk along the river to the castle and all the attractions in the new town or old town. There are plenty of bars, restaurants, coffee shops and stores in Andel close to the apartment, but our mileage varied quite a lot on that as we got a bit of a feeling some places didn't appreciate tourists - even well behaved ones who try and speak Czech! That said, the food and drink everywhere the hosts recommended was superb.
