Shawn was very welcoming and fun to talk to, and he gives solid travel advice. (Burt, the cat, is a fun fellow too.) He gave my room total privacy during my stay, but always offered a cup of tea if we ran into each other in the morning. The room was clean and great to come back to after a long day out. While the apartment is made for people taller than I (I'm 5' 4"), I could easily store small items in the cupboard or fridge, and my room worked well for me.
One note, the bed is quite hard, even for someone who likes a firm bed. I got used to it over the course of my stay, but might be worth noting for those who are sensitive to that sort of thing.
Overall, I think the location (3 min walk to two of the faster underground lines) and Shawn's hospitality were the best things about this place.
