Our stay at David’s apartment was perfect. Co-host Ivo met us and was very friendly and welcoming. The apartment is situated on the ground floor in a quiet inner yard with separate entrance. The place is huge and has more than enough space for 4 guests and can be also suitable for up to 6 people. S and U bahn station is just couple of blocks away, trip from/to Tegel airport takes about 30 minutes (if there is no serious traffic) and you can walk to city center for about 20-30 minutes. The apartment has everything you need including all kitchen utensils and extra towels and bed linen. It is nicely decorated with some vintage furniture and paintings. Retro radio receiver with surprisingly good sound was our absolute favorite, we enjoyed having breakfast listening to German radio :)
I would definitely recommend this place to anyone, it made our stay in Berlin very comfortable.
