The best host you could ask for! I stayed at Saido's apartment for about one month, and I have to say I have had my best airbnb experiences so far. Saido is not just a host. He is more like a friend to me. He put a lot of effort to make sure that I have a pleasant stay in his apartment. The location of the apartment is perfect. It is located in a residential area and it is quiet and convenient. There are three U-Bahn stations within the walking distance, and there is a grocery store just right next to the apartment. The bed is very comfortable, and in the kitchen you'll find pretty much everything you might need. There's also a big balcony though the weather in Berlin wasn't good enough for me to utilize the space much.
Unfortunately this place has been booked by another guest in April. Otherwise I would definitely continue to stay with Saido's place. I am very lucky to find this apartment and meet Saido.
Again, I highly recommend this place for anyone who's visiting Berlin short term or long term. I am certain you'll like the room and the hospitable Saido!
