Communicating with Bart was very easy. We didn't meet, but his friend Rene was there to meet me on arrival and to show me around. During my stay he was available by text and dealt with a query rapidly.
The apartment was lovely - really well presented, very clean and with everything required. It's a lower ground floor flat, but light and airy. The location, just a few minutes from the underground, was perfect with great local shops and restaurants. I'd really recommend it as a place to stay.
