The main problem was communication with Marco (we didn't read comments and we should have). He brought us a lot of stress with compulsive and numerous messages where as it could have been way simpler. Apparently he got bad experiences by the past but that doesn't excuse the way he despises his guests and the whole humanity (Neanderthals he loves to call them). the mandatory 30 minutes of explanations could be reduced. The few interesting element on history are flood in numerous useless informations.
The apartment itself was well described : a mini flat. nothing to complain about except may be not a good mattress. to finish on a positive note : the building is gorgeous and well located.
