Sunny was great! We got into town early and she was able to get us in before normal check in time, the flat was clean and functional, she even brought milk and fruit.
The location was good, close to everything we wanted to see (within a few minutes on the bus), 4 blocks from the green bus tour route. The only negative would be the noise, just normal street noise; but a little jarring if you aren't accustomed to sleeping in the city.
