We stayed at the West Side Inn in 2010 when it was named HEM Amsterdam Hotel, and that was a good experience so we decided to try their new extension Toko at 50 euros/night which is really cheap for Amsterdam. Part of the challenge with this hotel is finding it so as we already knew how to find it that wasn't a problem. If this is your first stay I recommend you enlarge a Google Map, find Delphiplein shopping center, and then it is just a matter of walking under the A10 freeway.
The Toko has been built on the freeway side of the main hotel. The construction materials must comply to Dutch standards but seem a bit flimsy, like the hall floors sway a bit when you pull heavy luggage. My lady said it made her feel seasick. The room is small, we tried to measure it and found 2,8 by 5 metres which is 14 metres total of which the beds take 4 metres and the bathroom another 4. The toilet is so close to the shower wall that you must sit at angle to use it. The lights are like 15 watts which is crazy because the lights in the hallway are at least 100W. The TV didn't work at all but the next day they replaced it with an apparently brand new one. We were there 3 nights. On the first two mornings the hot and cold taps were like cold and colder reminding me of Russia 20 years ago. But after we had rearranged our showering to evenings I found on the third morning there was plenty of hot water despite more guests, in fact I suspect they made more hot water available because there were more guests.
On the plus side, the room was very clean and we got new towels every day. Although the room was small it was adequate and if you want a bigger room try the main hotel. We liked the small breakfast for euros 3,75 which includes a hard boiled egg, bread roll, separate croissant, ham and cheese plus butter, jam and choice of coffee or tea. The 24/7 takeaway counter offers good pizzas plus sandwiches all the way to steak dinners at 21 euros. They sell bottled beer plus there is a bar open until quite late. There are tables and benches in the garden outside the hotel you can use. But in the Delphiplein around the corner there are two grocery stores the LIDL and a more expensive one. There is a Turkish fast food place which has a platter for one at 12 euros but they are happy to serve two sharing it and it comes with two chicken shishkabobs, two lamb chops, two pieces of steak, lots of salad and French fries and if you can find a cheaper meal for two in Amsterdam show me. You can walk to the Tram 2 which takes you directly to the Rijksmuseum and Van Gogh Museum or you can use the metro 50 at Heemstedestraat connecting to Leylaan then to either Schiphol or Central Station. Unless you have a car it pays to buy a rail pass at Schiphol for 1-3 days or longer but be aware they don't include bus travel. Altogether we enjoyed this stay but maybe it was because we like the parent hotel and we already were familiar with the area.
