Lucas rum is very cozy and beautiful. The apartment is near at the center which is accessible by buses, trams or on foot. The neighborhood was quiet. The heat in the apartment was ok and we were provided with a very warm quilt. The bed is very comfortable. Our stay was pleasant. We were provided with all the essentials both in the small kitchen and in the bathroom.
The only drawback for me was the communication with the mother of Luca, who is accessible via the phone and she replies late to the messages through the internet. That was a little inconvenient since it wasn't easy for us to call in Brussels because of high charges. However, she was very helpful and nice during our 5 day stay in the apartment.
All the rest was perfect! I totally recommend Lucas place for your vacation in Brussels!
