Yvonne's place was in such a perfect location for us, bus routes nearby as well for those who would like and the tram stop only 15 minutes walk down the road. There were some excellent cafes in the local area. Lots of excellent curry houses too!
The place is perfect if you want somewhere to sleep and then explore Edinburgh. It was a bit cosier than we anticipated. On arrival, the house was very clean and Yvonne's communication about how to get into the flat was great.
I think one of the downsides was the noise. When other people that live in the block of flats come in, it is very loud, you can hear nearly every footstep and conversation in the hallway, on the stairs and the flat above. The bed frame is also very noisy and interrupted our sleep, which is a shame. (The noise is why I haven't rated this as 5*)
