Tim's apartment is as central as can be, no exaggeration. It is right on Edinburgh's Royal Mile. Everything is in walking distance, including restaurants, pubs and shopping. It's beautiful and luxurious, the jacuzzi bath was amazing. The wi-fi is brilliant and didn't cut out or slow down once. An added bonus was that all the tvs (one in each bedroom as well as living room) had Netflix. Tim and his manager, Michelle, were helpful and fantastic. Michelle replied quickly at all hours.
I would greatly recommend Tim's apartment and wish to visit again sometime in the future.
