Sarah’s apartment was excellent! We stayed there for a week in July and were very glad we chose it.
The apartment is very clean and bright, much larger than what we expected from the photos and with a very beautiful decoration.
Checking in and out was very easy, contact was very quick both via the AirBnB app and the green messaging app as well ;)  We didn't get a chance to meet Sarah in person, but she was easily reachable using the app. Frank was very kind helping us check in.
The location is great, right between the Old Town and Vinohrady (where a lot of excellent cafes, bars and parks can be found). Most touristic attractions and a wide range of bars, restaurants, bakeries, currency exchange bureaus and supermarkets are close by. You can walk to most places, but if you don't want to get around by foot, there's plenty of means of public transportation within 1-3 blocks, we only used trams and metro four times, on some days when we had walked over 20 km (about 32 miles) and felt a bit tired.
The air conditioners (living room and bedroom) worked perfectly for summer hot days and nights, especially since the apartment gets a lot of sunshine! Also the washing and the drying machine were very helpful and worked fine too! The wifi connection had no problems either. The shower had good water pressure and temperature adjustment was easily adapted to what we wanted, and the red lights add a very romantic touch at night. The bed is comfortable and we had great nights of sleep there. The kitchen is fully equipped, though I suspect most people will eat out to enjoy the great food you can find in Prague (and the great beer).
Rental cost is very reasonable.
Highly recommended! Will definitely try to stay here again the next time we’re in Prague.
A final note: Sarah and Frank have prepared their own Prague guide - do try to visit some of the places they suggest! Excellent cakes were eaten because of their guide! Tasty Czech food was enjoyed because of it too!
