We stayed for three nights at Josef's apartment and had a very enjoyable time there.
Josef is a great host who answers your questions very very quickly - he is also genuinely helpful and super reliable: simply a fine host who wants you to have a good time in Prague.
The tips for getting to an fro from the airport to the apartment proved just right so the transfer went really smoothly for us (kudos to the Prague public transport system - everything went really well while we were staying there, and it is affordable too!). Several times it became clear for us that the apartment is really perfectly located for exploring the city by tram - and there are many restaurants, supermarkets, cafes, bars,... just around the corner too!
What is more, there is a quality bakery just downstairs which we chose for a lovely and freshly baked breakfast every day. We can recommend it very much too.
The apartment as such is clean and comfy, the kitchen is well-equipped (at least we found everything we needed for our breakfasts and snacking) and for the bathroom and shower lots of towels are offered too - everything looks just like the photos, so what you is is what you'll get.
The Wifi worked very well too, so, once again, we can only say that Josef has practically thought of everything and offers a super place for a neat stay in Prague. Although there was still some construction going on in the building while we were staying (in case you are sensitive to noise), we didn't feel bothered much and, honestly, everything else is s so perfect that you will probably not be bothered either.
We can absolutely recommend Josef as a host and the apartment he offers and would like to say thank you once again - all the best to you, Josef!
