The Sweets Hotel was a nice stay for a few days in Amsterdam. Our particular room was straight across the way from the main train terminal on the ferry. The room itself doesn't have A/C in it (just the upstairs living room area which we didn't use). However, if you prop one of the fans in the window, the temp at night is not bad! We were also surprised that people came to clean our room between the nights - as it was an AirBnB booking, but with hotel in the name, we shouldn't have been too surprised. The walk from the ferry to the room at night was a little tense - best for a couple, though we did not feel unsafe. Good balcony outside on the river to smoke if that's your thing.
