Everything was amazing! They always answer very fast all the messages!
When We arrive Otto was waiting for us on time! The flat was perfect; the only "bad" thing was that there werent coffee filters and sugar, and bath paper was not enough... Not important things!
Last day We had Our flight late in the evening and there were no problem to leave our baggage there all day, that was great!
Definitly, i would recomend otto and petra s!
