We met Katerin's dad on arrival and he was very helpful. He showed us around and did a great job. Response to messages was also very quick.
The apartment itself was OK - the bed we stayed in was a bit hard.
The location was great, as detailed it's close to town and the public transportation is very close by. It was also a pretty quiet area.
Should also note that we liked the heated floor in the bathroom and bedroom hallway - very nice when up in the middle of the night.
