Lux loft is in the center of the old part of the city of Antwerp. The view out the window is of the cathedral which plays the carillon for an hour at noon every day (at least when we were there). You step out the door and are literally in the vibrancy of the city with the big square (with statue the of Bravo) and the Meir (the big shopping street) right around the corner.
Everything you need is nearby: grocery store, tram, quaint restaurants.
The loft is well appointed and the hosts welcoming with a bottle of cava and coffee/tea supplies. The loft overlooks a square filled with cafes, open late at night, so if you are sensitive to noise, you do need to be aware of that. For the majority of the nights (we stayed 12), the dual paned windows and ear plugs were sufficient to not have our sleep disturbed by revelers. We were there during the height of the summer too, so other seasons may be very different. The host Petra checked in with us via SMS and was responsive when we had questions. We would definitely stay there again.
