The place is perfect! It is close enough to the city centre (20 minutes walking through a nice park) and well located in an atractive neighbourhood (nice shops, restaurants and coffee shops). If you don't feel to walk there are many buses that stops just around its corner.
The house has everything you need (everything is new in the kitchen, you find good towels in the bathroom, also books and games in the living room). The main bed and the portable in the living room are very confortable and the house have a good heating system. Wi-Fi is perfect in the living room and reaches the bedroom with enough power.
Gabriella is a thoughtful owner. She is giving lot of useful tips even before you arrive to the city. We had an interesting chat with her about the city and the people during the check in (she was very punctual).
I think it would have been very difficult to have chosen a better place to spend our holidays in Edinburgh!
