This was perfect for me: a functional apartment in a very well-kept building and very good value for money.
Siyuan was extremely helpful and responsive when needed - and only when needed: a perfect host!
Bascule is not Jourdan or Flagey, but a two minute walk at Patton there is a friendly and good-for-people-watching café called Steven's, and within a further short walking distance you have Ave Louise, Bois de la Cambre, Chatelaine etc.
Siyuan said she is about to renovate the place so a few minor glitches re cupboards etc will be corrected.
I will certainly check first if it's free when next I need an Abnb in Brussels.
