We had a nice stay at Paolas appartment in the centre of Edinburgh. Paola is very attentive, she answers extremely quick when you have a question. The flat was clean and there was everything you need. The bus station is close, also a supermarket, but you can also walk into the centre. I would recommend not to come with four people as we did. I think for two people the appartment is perfect, for four it's a bit small and the couches are not so convenient. But all in all everything was fine!
