What a great find! Eva's apartment is in the perfect location, easily walkable to all the sights (including Christmas markets!), and very close to the U-bahn for those who don't prefer walking. The location was quiet (though light sleepers like myself may want to bring earplugs and a sleep mask), but very close to everything - perfect!
The apartment itself was very clean and comfortable, with thoughtful touches like toiletries, coffee pods, and even a bottle of wine provided. An incredibly helpful touch was the portable wifi pod, which may be helpful to other guests depending on your mobile data plan. We were able to take wifi with us while we were out and about!
Eva provided helpful recommendations and was in touch throughout the visit, really flexible on our arrival time, and even let us leave our luggage for a few hours the last day so we could do some sightseeing. I would definitely stay here again and recommend this place to friends!
