I called the number several times, no one answered the phone. No clear check-in procedure had to ask the police in the train station to find out the check-in point. Something looked like surveillance camera in the living room and bed room, no one explained and answered the email about what these devices are and if they are turned off, if they agains the privacy of guests. The location is good. Near to tram, metro. a lot of places to eat around. you can not sleep with open window due to the noises. Aircondition has to be used during night to sleep well.
