I planned an European vacation for overworked friends, which included a stay at Willian's property in Amsterdam. He was quick to respond to questions, and provided detailed information.
I'd highly recommend Willain's property, and my friends have passed along their comments as well:
This apartment is in the Jordaan section of Amsterdam, which is really beautiful—quieter than the central hub and very charming. It’s one of the most desirable sections of the city, and at its heart (a few minutes’ walk from the apartment) are lots of terrific cafes and bars.
Views from the balcony are great. The balcony itself is wonderful, the best spot for morning reading and coffee, and essential to letting in the breeze.
The place is spacious and light-filled, with beautiful old windows lining the main room. However, these are painted or screwed shut, which is why the balcony doors are so essential to getting in air.
The bedroom could use climate control. The window (not adjustable) is lifted slightly with a block of wood to allow breeze, but not much comes in. What does come in are mosquitoes, which necessitates covering fully up with blankets, which then adds to the heat problem.
A portable cooling unit vented to the outside (similar to the one provided in the main room) would solve the problem, but would require rearranging the room a bit, which is very tight.
The bathroom and shower are great, plenty of hot water. The washer/dryer came in really handy on a three-week trip. The kitchenette (no range/oven) was just what we needed.
Our host Willian was great and very responsive.
