Robin's apartment is in a fantastic part of Berlin - plenty of vibe and easily accessibly by foot or tram. Plenty of local bars and restaurants which were amazing.
This apartment has a lovely view (5th floor), plenty of space and everything you need to stay comfortably. I stayed for 5 nights. I didn't use the balcony as I was out all day - but it is a winner on warmer days!
The fact that this is Robin's home means it has life in it - books, CD's, pictures, art, a comprehensive kitchen. So much more than an empty apartment or hotel room.
I cannot recommend it enough and would certainly be back on my next visit to Berlin.
PS Oh - the bed is so so comfy too!
