Great, central location, easy to reach by car or public transport. Unlike other reviewers, I did not hear any noise coming from the street, and I stayed there in a week where Porto was being invaded by Dutch, Swiss and English lads for the UEFA Nations League finals, which kind of speaks for itself. Smoothest check-in ever. The recently remodeled apartment was sparkling clean - I'm talking professionally-cleaned-clean. Plenty of nice touches designed to make your life easier: probably the first apartment I stayed in that had a plug adapter for multiple plug types, an abundant supply of power sockets (I'm always pleasantly surprised when houses are designed for 21st century folks), the internet connection is flawless, and there's even a state of the art Sonos One speaker so you can annoy the neighbours with your terrible music taste! Great decor with nice artsy touches - you won't find cheap, low-quality mugs and dishes here. But the star of the flat has to be the superb combo of one of the best pillows and mattresses I've ever slept in. The only downside about the Crimson Apartment is that you'll want to stay in bed for longer than you should, so book an extra night if you really want to see the city properly.
