Bottom Line: I recommend w/o hesitation and would certainly consider returning as Damien's guest.

Apartment is entirely as advertised -- very attractive space, comfortably furnished, well maintained, extremely convenient location for both downtown business and access to restaurants and activities. As is obvious from the photos on the website, this is a first floor ("premier étage" -- not street level) apartment on a busy street. But soundproofing of windows etc is excellent.

Damien is an extremely attentive and responsible host. Pre-visit contacts were very prompt and filled with useful information. On arrival, I found a very nice welcome basket of treats to eat. Damien and his local agent (Damien lives far from Brussels) were accommodating of my schedule for both arrival and departure times.

We had several unusual difficulties, but Damien dealt with them all with full attention. Specifically:
(1) Damien's ISP had no internet service to the area for the week, but Damien arranged for a telephone with hotspot access to be delivered the apartment. The result: instead of no internet in the apartment, Damien gave me mobile internet to use throughout the city at his expense.
(2) I had trouble with hot water one morning, but Damien responded within a few hours to address the problem successfully.

The only real negative was my arrival experience. Damien had gone out of his way to assure I could get into the apartment earlier than his usual check-in time, early in the morning immediately after previous guests left the same day. But when previous guests left keys locked in the apartment, Damien's local agent did not have a spare set. The result was three hours delay in getting access, with an hour of that spent by me outside waiting. I believe, however, Damien will have corrected this easily by ensuring a spare set of keys is in the hands of his local agent.
