Tina's place is exactly as described in the pictures. The room is really big with high ceilings and lots of natural light. Complementary tea and coffee facilities including a fridge. I was warmly welcomed by Tina upon arrival and we had a nice chat in German and French :-). It is super central, just minutes away from KaDeWe and Wittenbergplatz. And yes, upon arrival, there is a personal letter waiting for you including some restaurant recommendations nearby and one evening I went to the suggested Vietnamese place around the corner which I can highly recommend. I would definitively stay at Tina's place again!
