There is a 'hotel bus' that makes the rounds to various hotels, including the Leidseplein major chain hotels (Marriott).

The only downside is if they go to Leidseplein area last, you have to wait.
On getaway day, if you just want some slack and don't want to deal with public transport, Melody Taxi is CHEAP, like €29 from Eric's to Schiphol. Eric can call them for you if you don't have a phone.
It's a short walk from the Marriott to Eric's. If you plan on using the tram, get your 7 day pass (new version, used to be only up to 4 days) for only €30 at the TI office in Schiphol. Otherwise you would have to make your way back down to Centraal Station to the GVB office to do that.
You'll need to go to the TI to get the shuttle ticket anyway, might as well get the GVB pass there as well.
7 day unlimited GVB pass for €30, yes sir, that is a great deal.
BTW as you look out Eric's window across Prinsengracht, that little brown cafe across the way is tiny, authentic, and a great place to grab a beer or even lunch.
Make a right turn out the door and in a short time you are in the Nine Little Streets (Negen Straatjes) shopping area. Check it out on Saturday morning if you can, it's a three block square area of coolness.
Edit: ask Eric about using the washer and dryer downstairs. Saves a lot of luggage space on a long trip.
Edit: the snow is melting here, it feels like spring today, and I AM JONESING FOR AN AMSTERDAM TRIP IN APRIL. ARRRRRRRRRRRRGH. I'm quite sure you are familiar with the feeling
