Thomas is a great host - fast in his responses, flexible and a fun written instruction manual.
Although the apartment js rather small it was a great fit for our company of three. Lovely roof terrace! The regular bed was great and so was the sofa bed (unlike their usual reputation). Nice location with everything within walking distance.
Only downsides: stairs up to the apartment and small toilet, expect to poop with an open door ;)
Stay in this apartment is recommended!
