Yvonne's apartment is a great place to stay if you're looking for a house in Edinburgh. The location was fantastic, just a minute's walk from the nearest bus stop and about 10 minutes from the city centre. The house itself was absolutely comfortable, perfect for 1 or 2 people. Yvonne herself was there to meet us when we arrived (and met us early as well, so we could leave our bags there) and had a ton of useful books and leaflets about the city.
The only thing I would comment on is that the house got a *bit* noisy at night (from the neighbours) but it didn't last very long. Apart from that, we had a really comfortable stay there. I'd happily recommend this apartment to anyone else looking for somewhere to stay in Edinburgh.
