We had a great stay in Anna and Marnix' apartment. The apartment accommodated 5 persons easily and offered everything that was required for us. We were staying during the New Year so we used the heating system which was okay. The neighborhood is nice and friendly.

The faerie (which is free) that leads to the central station is in a 5 minute walk.

They also offered guides and maps of Amsterdam which might come in handy if you come unprepared :)

I would recommend this apartment to any group of people that would like to visit Amsterdam! Cheers!
