Nicole’s apartment is a gem. Cozy, with lots of light, spacious, comfortable, it had everything we needed (3 people) for our 4 day stay in Berlin. It’s well located, in front of the tram and very close to nice restaurants and bars. Bedrooms and bathroom are very comfortable as well and it also has a nice patio balcony which we unfortunately didn’t get to use because of the weather.
Only “but” for anyone reserving: be mindful that you will need to walk 5 flights of stairs, as there is no elevator. But it’s definitely worth it.
