Zachar's place was great! I primarily booked because I needed a a place quickly, since I had a bad experience with a previous Airbnb. I booked at 17:45, and at 18:15 I was already able to check-in! The place is small, but it's clean and has everything you need. It has more of a guesthouse vibe than a hotel, the walls are pretty thin, so don't plan to stay in your room for the whole day or work from here, but it's <2 minutes away from the UBahn, and it's in a very vibrant part of the city. Definitely would recommend, you won't find any sudden discomforts or inconveniences here.
