I stayed at Sofi's place for a week in December. The place was well put together, and all the amenities were there. Sofi was very nice and helpful during my stay, and although we didn't cross paths much at all (due to our schedules) she was very helpful when it came to instructions.
The initial check in was smooth, and I ended up picking up the key from a trusted shop down the street. Check out was just as easy, where it was clear what she wanted to happen.
The neighborhood was nice, and it was about a 7-8 minute stroll down to the L-Train (which is what I was taking). Plenty of shops and diners nearby.
The neighbors in the appartment building were a little noisy with music when I first arrived and here and there throughout the week, but when it came to cerfew time everything was quiet, as well at the streets around. I was able to sleep with the window cracked (as I like my room a little cool), and there was not much noise at all.
Overall a great stay. I would definitely come back!
