Oliver was always available to answer any question that I have had. He has kindly arranged our transfers from/to the airport, and took us for a quick walking tour around the city upon checking in and always provided local tips. The place was comfortable for a short stay - the room was clean and nicely decorated. The room did not have much sunlight, and there were no windows in the bedroom but we were mostly coming to get some sleep so this was not an issue for us. Location of the place is also very convenient. Bus stops were very closeby, there were some cafes/restaurants, and a lot of small bays 5-mins away from the premises.
There was only one problem we have had: I had to check out a day before my planned checked-out date, and I informed Oliver of this last minute change within 48 hours of making my reservation with him. He told me that he will refund me for it. So I did not bother cancelling my reservation with him thinking that it will be ok. In the end, he did not refund me despite promising that he will. So I will be hesitant staying in his place again, but if you book smartly and don't take a stranger's word on financial matters I think you will have a pleasant stay at Olivier's place :)
