2 bicycles in Amsterdam to lend anybody?:)

Hi everyone!

Me and my boyfriend are going soon to Amsterdam for a couple of days and unfortunately we will have to leave our bikes at home. We are already dreading the idea of walking around the city instead of cycling:)  The rental prices are a bit of exagerration for our budget so we are turning to Warmshowers community for help:) Is there anybody who would have 2 spare bike to lend us for 2 days while we are in Amsterdam next weekend 23-24 September? Would be awesome:) 

Thanks,

Nina and Matthieu
