The host is lovely. Nice area, very quiet.
Transport links to north of island - free ferry go through central station (there are two walk ways that do not require a ticket, walk through to ferry side and it was the NCP (If i remember) ferry furthest to the left. It’s a 15-20 min walk from there. Alternatively (especially first day with luggage) catch 35 bus (area D up the escalators) get off at Ponastratt (forgive me if that not the correct spelling) turn left off the bus and the place is a couple of roads down. Transport is excellent is Amsterdam. Do not be put off that its north of central.
Good nights sleep at Nima's, everything you need is available. Other people are in the house but we never saw them and there was no queues for the toilet or shower.
