The stay was great, I spent almost one month there and it was great. The room is really tidy and very clean, also the house is super clean. Mercy is a great person, warm and very helpful. She gave many advices about the city and the life in Edinburgh. The place is not far from the center, you can reach the center in 30 minutes by bus and there is a big supermarket in the neighbourhood. Highly recommend to stay at Mercy's place.
