I recently had an excellent stay at Ivy's place. The bedroom and shared areas were sunny, clean, and well-maintained. The place itself is just a 5-minute walk to the Brixton tube station, with many convenience stores and restaurants nearby. I felt safe in the neighborhood walking alone at night. I also appreciated having breakfast in the morning, and Ivy was delightful with all her travel suggestions.
One thing to note is guests would share Ivy's living space, learn her house rules, and interact with her often. I can see why this might not work for everyone. Fortunately, I am very comfortable with this, and so all in all, I had a great time!
