We had an excellent stay. The apartment is beautiful, cozy and warm, with a lovely view. Minimalist, yet tasteful, it was worth the fact that it's a bit off the city centre -- but still it's not too far, one can be downtown in 20 minutes by public transport.
Excellent heating and warm water, all the amenities one can need (kitchen, bathtub & shower, washing machine), a lovely living room with many interesting books and two spacious bedrooms.
Tim & Klara were extremely helpful from afar and provided valuable info in their welcome book.
And Zuzana, who was there to meet us, was lovely and provided anything we needed with utmost privacy.
All in all we would definitely choose this apartment again and recommend it, especially for long stays in Prague.
