Oliver's place is in an awesome location, so you won't be needing the public transport and you can walk anywhere you want. Also Oliver response time is amazing, like within minutes, so we always felt secure in sense any problem would arise we could reach him very fast.
The only problem is the size of the place, the bedroom/kitchen is really tiny, and the bed can get a bit uncomfortably small for two people. It's ok for a short stay of few days, but if you're staying for 5 days, a week or more, I would suggest getting something bigger. Also the place was not exactly the cleanest when we arrived, but it was still clean enough, so no major complaints there.
