Thank you Mario! Absolutely excellent. Mario met with us and showed us to the apartment, which is down a quiet lane, but still very close to the centre.
At the apartment he has maps / tourist guides and small amenities to make the stay much easier!
Everything was excellent, including little things such as him allowing us to store our luggage in the building and borrow the spare key even after we had checked out.

Highly recommended, thanks again - will definitely be back!
