The flat is incredibly well-located. I didn't use any trains while in the city, because the walks to and from his place are all very awesome and safe. The place is exactly as advertised, and since this is important to me, the bed was actually comfortable. The floors are mostly original (some 200-300 years old?!) and the flat has a lot of character.

I didn't spend much time hanging with Rainer, but we did get drinks on the last night I was there, and he's got great character. He is a trustworthy guy, that made me (as a lone traveler) feel comfortable.

The neighborhood is very old (it's the 1st district) and is where all of the action is. Plenty of good restaurants and cafes nearby.

Thanks for the great stay Rainer!
