Me and my two friends stayed at David's place for a weekend. We had such a good time. His apartment is really beautiful and really equips everything you need. It has a great big kitchen, something which is often hard to find and a beautiful living room. Communication with David was really good as he informed us about everything on time, and even during our stay the questions we had were answered really quick through email and texts. During check-in he explained everything about the area and told us about the places to go. It's a really nice area, there is a small square on a minutes walk, which had a very nice small market. As Olso is not so big you can actually walk from his place to the centre and otherwise there are loads of trams around. There is also a beautiful small waterfall up the road and there are loads of restaurants and small shops around. I would say the perfect place for a city trip to Oslo.
