We were very taken with this unique flat; with the cut of the flat, the furnishings, the location, the courteous nature of the host and the whole uncomplicated process. We will definitely recommend it to others!
However, one thing should not go unmentioned: The street noise at night. Of course, this is not the host's fault, but we think that this information could be useful for future guests.
The street directly in front of the house is very busy—which doesn't bother at all during the day—but at night it is sometimes sleep disturbing, because sometimes even at three o'clock in the morning rattling motorbikes or passing cars with music at party volume tear you out of your sleep. We know this from Greece, so it was nothing new for us. Interestingly, however, this noise decreased considerably at the weekend—something we still can't explain. Maybe the party people drive a different route at weekends? Whatever. In any case, we quickly got used to it and it didn't detract from our stay.
Otherwise, as I said, we were very pleased with what awaited us. Extra praise for the host's flexibility and responsiveness to minor problems or questions.
