We had a really nice stay at Lin’s apartment. It is less than 10min to the next metro station from where we travelled the whole city. Since the apartment is Lin’s home, it is well equipped. Sometimes you can hear the neighbours in some of the rooms but the sleeping room is very quiet. We did not meet Lin in person but the communication was great throughout. Maybe good to know for non-Europeans that you will not have WiFi at the apartment which was no problem for us at all but could be difficult for others.
