Martina is indeed a superhost, she waited for us and even went to meet us at the tram when we didn't know where to go. She was available all the time and gave us clear instructions to get to the apartment and to the airport the day we left. The place is amazing, clean, big and very comfortable; perfect for my mom and aunt to rest at the end of a long trip. It takes around 15 minutes to go to the castle walking, but to get to the center it takes about 30 min in total (walking+tram ). So depending on the objectives of the visit to Prague, this might be the perfect place. I think it's not ideal if you want to experience nightlife, but for the rest it's the right balance between comfort, quietness and tourism. Also, it's on a hill so it allows to have very nice views of the city.
Thanks Martina!!
