Glenn's flat was spacious, comfortable and really well located. The living room is very comfortable and relaxing, and the kitchen/bathroom has everything you need. The bedroom was cosy with a very comfy bed. You might need to leave your bags in the front room, as storage space is relatively limited in the bedroom but that's absolutely fine. The street was quiet and we were not disturbed, and managed to sleep very well.
In terms of local amenities, there are lots of cafes and nice places to grab a bite to eat near by, and the walk into town is a nice easy stroll through the meadows up to the castle and the Royal Mile, which took us about 20 minutes. The flat is also a short walk from Arthur's seat, which is great to hike up on a clear day.
I would thoroughly recommend Glenn's flat for anyone coming to Edinburgh, particularly with a car over the weekend. On street parking is available and free from 4:30 pm on Friday to 8:30 am on Monday. Outside of this timeframe, parking per day is paid for on an hourly basis.
