Krste is offering a great place in the heart of Prague, with a great value for money.
We liked spacy and bright apartment, it was fully equipped, there was plenty of space for a family with two small kids. It's in the fourth floor, but for us it wasn't difficult to climb the stairs. It's looking towards a hostel (and a construction site at the time of our visit) but it was quiet enough we were all able to sleep without any problems.
Krste is really nice guy. His responses were very fast, he helped us a lot and I'm sorry we run out of time to have a coffee with him. I wish him all the best!
