My best recommendations for Hana's apartment. It's on quite street in Mala Strana. We've stayed a week, and did not use transport - 10 minutes and you are in the Castle, 5 minutes - Karlov bridge, 20 minutes - Strahov monastery, 1 minutes on Nerudova with plenty of places for morning coffee.
The apartment is very comfortable and clean, nicely decorated, a thought is given to every small detail. Perfect rest after all-day strolls. Check in/check out is automatically and convenient.
Hana is very kind and generous host. As our arrival time was late, she left for us really huge dinner.
Many thanks, Hana, for your hospitality!
