Staying at Martin's apartment was a good experience! We had good communication about the check-in and out beforehand and he was flexible when 2 of us arrived earlier than the other 2.
The apartment indeed is cosy, so being there with 4 people sometimes the apartment felt a little too small. We would recommend staying here with 2 or 3 max. Other than that the apartment was clean and the kitchen and bathroom are very modern and have all the comfort you need.
The location of the apartment is very nice. Free parking nearby, and a 20 minute walk to the city center. In the close neighbourhood of the apartment there are some nice bars and restaurants as well.
Only things we liked less were the fact that the bedroom doors woudn't fully close and there were no curtains to make the bedrooms a little darker. The double bed was a little cosy as well for two people of nearly 1.90m and did not feel very stable at times.
Overall we definitely recommend staying here!
