My wife and I stayed here and loved the small side-street area it was on, a cute walkable cobble-stone road right off the road in to Old Town or other directions for great restaurants, parks, etc..
The host Grant was very proactive in coordinating with us, being friendly and available even with the booking being around the holidays which we know isn’t easy.
The flat was nice and spacious, with two full bath and beds being a great convenience. It heated up well and it was handy to have control of the air and water heat.
The location of Old Town is definitely our recommendation for a quieter stay in Edinburgh while we walked back from New Town, past the castle, in just 15 min. Fully recommend this apartment and it’s host Grant.
