We spent 2 nights at Jeroen’s apartment in October, 2018. The whole experience was definitely positive: Jeroen was very friendly and willing to help. He gave very clear instructions on how to get to the apartments and provided advice on the shops, transport and bike rental near the house. The place itself was very cute and cosy. We had everything we need. The terrace outside was wonderful - I wish I spent a couple of summer evenings there )
Transport connection is fine. It took us 20-25 minutes to get to the city center (central station) either by tram or by bicycle.
I recommend staying at Jeroen’s place when you are visiting Amsterdam!
