The flat is bright, spacious and in a great location - Tollcross has many options for cafes and restaurants. There was some communication from the host just before our arrival to tell us about a complaint from previous renters about a noisy air conditioning unit on the side of the building where the bedrooms are. We were given the option of cancelling our visit but we were a few hours from Edinburgh by that point. We didn't actually find the noise to be a problem but I'm mentioning it because I think it could potentially be if you happen to be a light sleeper!
I would also say that it would feel like better value for money with a few added touches - more pillows on the beds and a few basics in the kitchen would've gone a long way. Apart from that, I would recommend!
