Krzysztof's apartment is great, it is perfectly located in a very safe part of Brooklyn right off the Graham stop of the L subway which brings you directly into Manhattan. It is a 2 minute walk to great cafés, grocery stores, bars, restaurants and multiple laundrettes. The apartment is also within walking distance from Bedford which is an uber trendy part of Brooklyn right by the waterfront, full of cool shops, restaurants and bars.
The apartment itself was ideal for us (3) with the double bed in the bedroom and the convertible sofa-bed in the living area. The kitchen was fully equip with everything we needed, including a brand new smoothie maker and French coffee press. Krzysztof even stocked the kitchen with plenty of coffee, tea and bottled water for us (even though New York water is super clean and more than okay to drink!).
The apartment is cozy and the Smart TV was ideal for when the weather was poor, while the rooftop deck has a spectacular view of the Manhattan skyline where we enjoyed many sunsets when the weather was good. The only downside is that it is located right on a busy highway so it is generally quite a loud area but we quickly adjusted.
Overall Krzysztof's place is great, he is an excellent host who is always on hand to help with any queries. I would definitely recommend staying here, we really enjoyed our 3 month stay!
