We had a great time in Antwerp and slept in a room for three in Leonardos appartment - very, very clean (just like the bathrooms) and comfortable. Leonardo and his son which we met were very friendly and told us always to „feel free“.
We reached the centre with public bikes (Velos), one station is very near by the appartment (2-3 minutes), so it was no problem that we stayed not so central.
We really recommend a visit!
