I was staying in Vanguard for a night on July 4th then i was heading for paris the next day. Gijs was not there but he arranged everything before i arrived. His friend, Derk , is a very nice young guy and provide assistance all the time. i took the third floor room, with a relative big bedroom with a small sitting room attached, where you can enjoy the tea with the beautiful view of canal. The bathroom and toilet is separate, super clean and with everything you need.
The location of the guesthouse is definitely a plus. Within walking distance, u can go anywhere of the major attractions. It is relaxing and very good residential area.
The next morning, the breakfast is interesting although there were some small mistakes going on. The salmon is very nice and coffee bright the day up!
I will definitely come back next time to Amsterdam!
