We really enjoyed our stay here. It's right in the heart of the city - and so in easy walking distance of shops, bars, restaurants, cultural sites etc - but also feels like an oasis high above the hustle and bustle of the streets below. The apartment is really nice - cool and comfortable - and the roof terrace - in fact two joined roof terraces - is a real bonus. A lot of the places we looked at on Airbnb looked a bit bland and characterless on the website. Whereas we liked the more individual and personal feel of Matthias' flat. We really liked staying in the centre and being close to the liveliness of the city but being able to retreat into the calm of the apartment and the roof terrace for some down-time. The apartment wouldn't suit everyone - there is a long flight of stairs from the front door then a spiral staircase - but i would definitely recommend it for anyone wanting a central place to stay with a bit of character. Matthias is an an excellent host with very quick communication and helpful local recommendations. We felt very welcome. We would definitely stay there again.
