My friends and I had a lovely stay at Martin's. It was super easy to get in -- Martin sent very clear instructions and, overall, he was very responsive.
Great location, very close to the city center, yet amazingly the flat was very quiet and tucked away near a small park.
Everything in the apartment was in tip top shape -- I just took one star off for some sticky glasses in the cupboard. Otherwise you could tell the place is well care for and regularly cleaned.
