The apartment is as nice as the photos show, it is comfortable and very easy to clean. All the domestic appliances work well and it has everything you need for a long stay. The Wi-Fi works great, I needed it for my work and the connection never failed. The balcony has a nice view and in autumn you can enjoy the sun until late afternoon. It has supermarkets, stores, and other basic services very close. It is very well connected by subway and train.
I found Oliver to be a very experienced host and his conciliatory nature made for a pleasant stay. He is kind, cordial, helpful, patient and very respectful.
If I were to return to Berlin, I would gladly rent this apartment again, which I consider to be very appropriately priced for its qualities.
