First of all, Mat is absolutely one of the BEST Airbnb hosts I've met so far. Very communicative and easily reached, he get back to his customers very quickly - and is very flexible with check-ins!
The place is a cozy and quirky apartment located right next to a subway line 7 station. If you're afraid of heights, you will probably have a problem with the stairs leading to the basement apartment. That being said, they could be a LOT worse, since we're dealing with Europe here. :-)
Pillows, bedsheets, dishes etc. are all provided. Overall I really liked the vibe of the place! The ONLY thing that was bothering me and my travel group was the lack of air quality in the basement. Mat had provided us 2 air conditioning devices, which definitely helped the humid odor and general stuffyness, but unfortunately they were impossible to use at night because of the noise they made. So for someone with asthma or heavy allergies this may not be ideal place - but again, apart from that you are looking at a very cool, not-your-typical-hotel experience with a STELLAR owner, who is happy to take care of you!
