Saša and the landlord were very nice and accommodating. Saša was not able to meet us right at the time we were getting to Prague, but was very helpful in communicating with us before we got there and was very nice and showed us around the flat when we did meet up. The landlord needed to stop in during the week we stayed there to get some things and helped us work out the radiators and water heater (we had accidentally turned the radiators off). The location is very central, with very easy tram access and walking distance to everything you would want to see in Prague. For a comfortable home base while you are visiting Prague, I would highly recommend staying here.
Our negatives: the washing machine did not clean or drain the water from our clothes, but Saša later informed us that we had just used the wrong setting. If you need to use the washer whilst staying here, I would recommend to ask Saša to show you how to use it. The flat is a bit loud and creaky--you can hear everything from the hallway and in and around the flat (although you can't really expect more than that from a converted attic space--the landlord did a VERY nice job converting it into a spacious and beautiful space). The beds did not agree with us, as they were kind of foam pads, but I think we have picky backs as this is not the first time our backs have not agreed with a bed in an Airbnb listing. The wifi was sketchy at best of times, which was not ideal as we were looking for a retreat to communicate with home in Prague.
Overall, this was a very nice place to stay. It is an excellent home base to see all the sights, and is very well equipped. The kitchen had everything we could have wanted to use including a nice coffeemaker, great hob/stove, and an oven.
