This place is great! Just as advertised. We loved it. Don’t let the exterior deceive you - the interior is just as pictured and it is very spacious and comfortable. While we did not meet Sarah & Matouš - they were very friendly and responsive.
I will mention that the elevator is very, very small and so if you have trouble with confined spaces or trouble with stairs - this may not be a good fit.
Overall we really enjoyed our stay. The apartment felt like home while we were in Prague. The design is very modern and the bed is comfy. An added bonus that the lamps also worked as wireless phone chargers and had a USB port.
The location of the apartment was so great as well. Being right at Wenceslas Square was so central and close to everything. We would definitely recommend to stay here and wouldn’t hesitate to return!
