Peri is an accommodating host and her flat is a delight. It has everything you could want and being a top flat is lovely and light. We liked being in Portobello- it is real Edinburgh- not the Royal Mile. Buses are frequent and take around 20-30 mins to Princes St. It was easy to park outside the flat but we preferred to take the bus. Lots of good eateries in Portobello and of course the beach and promenade is great for a relaxing walk.
Please note though, if you have any mobility problems you might find the stairs difficult.
