We had a perfect vacation in Prague! Jan and Sarah's apartment was comfortable, cozy, very clean and wonderfully quiet. All the amenities are of high quality and allow for a comfortable and pleasant stay: the mattress is excellent, the kitchen has everything you need for a basic meal, there is both a bath and a shower which is fun. The small, sweet terrace is great for a little breakfast for two.
We did not get to meet Sarah, but Jan was super nice and very kind, he gave us a lot of useful information about the city, restaurants and cafes, and saved us when we got stuck without a power plug adapter :-)
The place is highly recommended and the location is perfect, we walked everywhere and hardly had to use the tram (which is just a minute walk away).
If Jan and Sarah's apartment is available on your trip dates - do not miss it!
