My friend and I stayed for 5 nights at Mattijs's lovely home. He was incredibly prompt in answering all of my questions prior to arriving and made a point to connect with me throughout the day or 2 prior to our arrival so he could ensure he was there to greet us. In the end he wasn't able to as we were delayed but he left the key with a nearby shop owner and clear instructions so checking in was easy as pie. He came by later that day to say hello and check that we were comfortable and had everything we needed.
There are 3 flights of narrow stairs to get to his apartment so keep this in mind if you have any mobility issues. His place is bright, very spacious and in a great neighbourhood away from city central (what we wanted) yet only a 10-15 minute tram ride to most of the other neighbourhoods and tourist spots. There were lots of cute restaurants and shops nearby; a major grocery store as well as a great gourmet shop (Stach) are both a 5 minute walk away. We bought food to make simple breakfasts and his kitchen is fully stocked with cooking equipment if you plan on going that route. The bathroom can be a bit challenging if you're not used to the design of the shower floor being the same as the actual bathroom floor but it's fairly easy to clean. Would only have requested more towels as we only had 1 each for the entire stay. Oh and the bed is a queen size! Overall a great place that we would recommend to anyone!
