Thank you John that it was possible to book the flat spontaneous. John was not there but he sent us a detailed description where to find the key. The flat have a very good location in the heart of Edinburgh, restaurants and pubs can be reached within a 5 minutes food walk.
As we arrived the cleaner was there and showed us the rooms, their were big but unfortunately not clean. I asked he cleaner to remove the dust and the mould in the bathroom, but nothing happens. Except of this it was a great time.
