Dror was very cheerful and greeting host. He helped us with all the things. He was relatively nearby the apt so he arrived quickly when we needed his presence.
The location is superb - its on the quite street just by National museum - basically by the start of the most useful and longest tourist track up to the castle on other side of the Karl's bridge.
The apt is great. A bit better in real life than on photos. Two separate bathrooms is a pleasant bonus.
