I really enjoyed my stay at Numa. The location was great (check out nearby Saigon Food for delicious Vietnamese!), transport links are excellent and it was well priced. The room itself was stylish with minimalist decor, and the bed was huge and super comfy (note: it's a firm bed, which is why I liked it), though the pillows were too soft for my personal tastes. The rain shower was great too. Having a fridge and a safe was nice. I don't know if Numa was quiet during my stay or if the soundproofing is really good, but I didn't hear any noise during the night. I was in room 304; this is particularly quiet as it's on the back of the building so there's no traffic/street noise. Contactless check-in and comms were also handy. I'll be staying again when next in Berlin!
