We stayed at Vera's apartment for 3 days. She was very nice before the arrival while planning the trip. We have been welcomed at the apartment by Marina who gave us a warm welcome despite our late arrival (11pm). She explained everything we need to know and was very kind.
The flat is quiet, very nice and clean. The "jacuzzi" is definitly a plus after a long day walk. The neighbourhood is very quiet and you are 25/30mns far from the center, the Charles Bridge or the old town by walking, with a nice view on the riverside. If you want to visit the Castle, it's only 40mns away. We didn't use any public transport from the apartment but there are buses and the metro around the corner in case you need it.
So, as far as I'm concerned, that flat is perfect for a few days trip in Prague.
Thanks to Vera and Marina for everything, it was a great stay :)
