I have stayed at Martina's place several times over the last few years and Martina will always be my first choice when in need of accommodation in Prague. I had to stay at different places when Martina's place was booked but always come back when her apartment is available.
Martina is very friendly and helpful, her place is very clean, organized and easy to get to.
Quiet area but at the same time close to everything one needs. Highly recommended.
Could not wish for a better place to few days in Prague.
