Karl is a really nice host, he always reply fast, before we got there he already sent me detailed and accurate check-in informations. I didn't noticed this house was an basement so at first I went to apartment A which is upstairs, but then we find out apartment B is downstairs. The house is exactly same as the pictures, clean and bright. The only disadvantage for one bedroom close to the street is a little noisy in the night. On the whole, I have to say this apartment is really nice, recommend!! Thanks Karl.
