Martina is very friendly and helpful in every way. She knows a lot about the city and even brought me and the other two visitors to the Petrin Hill! I lived in one of her bedroom in her basement apartment for three nights. The room itself is cozy and she prepared a lot of drinks in the fridge for me to have, very very considerate! The location is perfect, just around like 15 minutes walking from the Charles Bridge. I enjoyed very much living there and would highly recommend Martina's place to anybody planning to travel in Prague!
