Thomas place is really spacious and clean and stylish. we loved that it was a lot of light coming in from all the windows. The bed was big and nice felt a bit luxuous and we had no problems at all with hearing the noise from the street even though this is really as central as you can get. (sweet thomas even provided earplugs and we slept like babies.
If you are first time in amsterdam this is the perfect spot- walkable from all central attractions and even amsterdam centraal. we felt a little bad livning in the middle of red light district but that is only our own opinion about the prostitution.
We love to party and because of that we will maybe choose some place else next time where we can make more noise in the night :) But we would defenitely recommend thomas place to anyone who sleeps normal hours and want to enjoy the heart of amsterdam! Thanks for a really nice stay!
