We had clear communications with Andrew before arrival and his directions to the house were easy to follow and we had no problems getting there as it is only about 10 minutes walk from the Central Station. The narrow street the house is on is very peaceful - you'd never guess it's just a minute's walk to to the busy main Damrak Street on one side and Dam square at the other end. Andrew was at the house to welcome us when we arrived and he spent plenty of time showing us around the house, which extends over 5 floors, with us using the top 3, one of which is a sort of mezzanine with a double bed which our kids loved sleeping in - really cosy. The next floor down is a very cool seating area with many interesting books - it was great to relax there with a coffee after our journey - the vegetarian cookbook and Richard Scarry's Busy Busy world were particularly enjoyed. We only had one night to spend as we were going on a biking holiday the following week, and Andrew gave us a map and marked out some nice areas for us to walk around the city's Jordaan area that evening and a great Indonesian restaurant to eat at - Kantjil en de Tijger, definitely recommended. We had a comfortable and peaceful night's sleep and cooked a great breakfast next morning from the things Andrew had supplied: eggs, milk, butter, rye-bread and with the added luxury of the Nespresso coffee maker with about 20 different flavours (we tried quite a few!), topped off with milk from the frother - delicious.
Everything including the showers/plumbing and kitchen worked fine, as did the Wifi.
Andrew kindly let us leave our bags at the house until the afternoon when we were heading off on our biking holiday.
If we visit Amsterdam in future, we would definitely stay at Andrew's place again for his warm welcome, the central but peaceful location, and because it's such a characterful and comfortable house. I would recommend it without reservation to others.
