My family and I have just returned from staying 5 nights in Neil's apartment in Edinburgh. Having never been to Edinburgh before we couldn't be happier with this place.. The apartment is in a perfect location in the centre of town, if you're arriving by train its walking distance. The place itself is exactly as described and huge. Plenty of space to move, especially when travelling with two teens as we did.
Neil is a great host, staying in touch with us before and during our stay to make sure we were comfortable and had everything we needed.
If you're staying on a friday or saturday night you can hear the lively and boisterous crowds partying on through to the wee hours - pack some earplugs for those nights. But thats certainly not a reason to avoid this place. We would definitely stay here again.
