I only met Felix and his roommate briefly, but they were both kind, and made me feel at home.
Check in and check out were easy, and Felix was able to accommodate earlier bag drop off. He was friendly and happy to provide suggestions for things to see and do in the city, and had some maps and brochures on hand.
The apartment had what I needed, and the bed was very comfortable. Some might prefer to be right downtown, but the location was perfect for me, with metro, bike rental, and grocery stores nearby. Walkable to city centre in about 30 min.
