Our stay at Ather's was great. We were there for 2 nights, and was warmly welcomed by him. Even though we were busy exploring Edinburgh and thereby were not home that much, we felt that Ather was there to help if we were in need.
We felt very much at home since we had a big bathroom besides the appropriately sized bedroom.
The apartment is located 30 minutes walk to New Town and 1 hour walk to Old Town.
