We are pet friendly. We have 2 big poodles. Gaby and Rudy. Most of the time guests comes with dogs. The rules in our house about bringing Your (in most cases) dog on a holiday with You, are the same as You have in Your own house. If You have well behaved dog and You clean after it, she/he can stay in our house at no extra charge.
In general, we prefer to have dogs in Apartment III. But, if it is a smaller dog there should be no problem to accommodate them in Apartments I and II.
Whatever pet You plan on bringing with You on Your holiday, please tell us in advance.
