My friends and I stayed at Carmen and Tom's flat for two nights whilst we were up in Edinburgh for our friend's baby shower.
We absolutely LOVED the flat. It is beautifully decorated and very unique. We were a party of 10 so the maximum for the flat but it did not feel cramped. The flat is in a good location, within walking distance from town (or a very short and cheap taxi) and there is also a lovely cafe opposite which does a great breakfast.
Carmen and Tom provided quick responses and were very helpful. I couldn't recommend this flat enough!
