My stay at Aletta's place was very nice overall. The area is quiet and the interior is very comfortable.
Communication was very reliable and I was given easy direction to find the place, plus plenty of good advice about areas to visit.
As someone who likes walking rather than using public transports, I'd prefer to be closer to the city centre. But the flat is still in walking distance from the centre: it may just take around 15 minutes to reach the outer canal on foot.
All in all I'd definitely recommend staying at Aletta's place.
