The place is perfect! The host, Josef, is more than perfect!
Josef is a well-organized host and very very helpful and reachable. Even though we arrived late at night and he couldnt meet us in person, our check-in was very easy and smooth, with the clear directions he gave and his support.
The apartment is easy to find with a tram station in the front and from walking distance to all sites on the other side of the bridge (as well as walking distance to the old city center especially if you like exploring the city on foot)
Also the apartment was so clean and everything you might need is there, prepared for you, ready to use (including an iron, hair dryer, french press etc.). There were small detailed touches that we loved; the variety of coffee and tea, toiletries, notes and maps for walking around the city as well as discount coupons and so on.
Josef helped us during our stay through whatsapp, with very useful tips and suggestions. As there are still places we would like to visit in Prague, we will come back and for sure we will be staying in this apartment (or any other of Josef`s apartments :)).
