It's an ideal option for a solo traveler or a couple. The studio is small, exceptionally clean, nicely designed, warm and pleasant and almost unbelievably inexpensive.
I did not meet Bonny, I was let in by her boyfriend, who is a very kind and cooperative person.
I am especially thankful to my hosts for providing, as a token of hospitality, not just usual tea&coffee, but also drinking water and even some food, which was most considerate, because I arrived late in the night.
Location is very good, close to both Central railway station and Florenz metro station. Perhaps those arriving by train should know that it is within 10-15 min walking distance, but finding the way for the first time might be a bit complicated, because what looks as regular streets on the map in fact are - in part - passages along or under highway roads and overpasses. Nothing terrible, just something to be prepared for.
The nearby area is inhabited by expats and students, so it is safe and friendly and, maybe surprisingly, quiet. Oh, and there's a 24/7 shop next door!
To sum up, I am very happy about my stay at Bonny's. Thank you!
