I've had a great experience staying at Liam's apartment. It's located in a nice, quiet and artsy area of Brussels close to the center and I've enjoyed walking everywhere, though there are many options for public transportation as well.
The atmosfere in the apartment was very welcoming and warm, and communication with Liam was good, he was friendly and helpful about any questions I've had.
Overall, it's a wonderful place and would definitely recommend it.
