Nicholas is a great host in all aspects. He gave us a very warm welcome upon arrival and some really nice tips on places to have dinner etc.
The first night we were staying at his apartment we had a 'low battery' issue with the CO sensor. While this can happen to anyone at any time, he went above an beyond to rectify this! He even provided us with a bottle of his own made wine (which tasted amazing, definitely buy some of him if you get the chance)! So while I would give him a 5/5 rating regardless, all the extra steps he took to make our stay as pleasant as possible, really puts his rating off the charts!
