I would describe Duncan as laid-back and professional, which is perfect as a host, especially since you'll be sharing the bathroom and kitchen with him.
The apartment:
+ Is very good value for money
+ Is both in a very convenient location, and in a quiet alleyway
+ The bedroom is considerably bigger than it might seem from the pictures
+ The apartment in general has a quite homely feeling
- The shower maybe isn't the most comfortable and old, although everything is very clean
- The kitchen, although clean and equipped, misses a kitchen table
I had an amazing stay at Duncan and would certainly recommend
