I stayed at Oliver's place with some friends and the location is unbeatable, really close to the cathedral. The communication with the host was really good as well and it's a recently renovated apartment. The cleaning could be better but all the furniture was new and with great style.
However, the building was in a really bad status (looked like avandoned), with spiral stairs that are difficult to climb with a suitcase (especially since it is 3rd or 4th floor without an elevator), and the light didn't work sometimes - so it was kinda scary . They are probably working on it though.
Overall, I'll recommend it cause it was a nice host, location is key and the apartment had a nice style.
