Erik is a very friendly person and the communication was really easy. A big plus for the availability of bikes to use during the stay! The basement (!) flat is very close to the centre and you can reach many areas within Minutes either by bike, foot or tram.
We stayed for 5 days and unfortunately had to deal with very loud floor boards from Erik's Airbnb apartment above during. Also it would've been nice to know that the apartment is situated in the basement. pros and cons included.
Overall I would recommend Erik's apartment for a short stay.
