Bed with a View was the perfect base for our short (4 day) stay in Edinburgh. The location is perfectly central and we got everywhere we wanted to be by walking (including the castle, Holyrood Palace, Arthur's Seat, The Meadows, Calton Hill, New Town/West End, Dean Village, etc.). The only time we needed a bus was to get to Leith.
The apartment itself is clean, nicely decorated, nice large bathroom and shower, and does indeed have a great view. The only downside we noticed was that the walls to other apartments are a little thin, so could hear taking and tv from other units in the evening, but we were so zonked at the end of the day anyway, it didn't bother us much.
Rachel was very prompt and helpful in returning all of my emails, even though she wasn't in Edinburgh at the time of our stay. John, who met us at check is was super friendly, welcoming, and helpful.
I hope Bed with a View is available down the road so we can keep coming back! :)
