I would recommend this place. It's in a quiet neighborhood, but still an easy tram ride away from Amsterdam Centraal station. There were 3 of us, and it wasn't too cramped. It got up to 100F a few of the days, but with the curtains closed during the day, it stayed relatively cool. The upstairs bed has separate blankets, which is nice for friends to share, and the sofa bed was actually quite comfortable. The kitchen is really well equipped: plates and bowls, lots of mugs, a blender, induction stovetop, coffeemaker, milk steamer, fridge with freezer drawer, and an oven/microwave. There is a full grocery store a ~10 minute walk away (and a little corner store even closer, by the tram stop) so it's a good place to stay if you don't want to eat out for every meal. We didn't meet Emilia in person, but she responded quickly to messages beforehand and let us check in early. Her friend who lives upstairs in the same building checked us in, and was very friendly and helpful.
