Our stay at Huan's place was perfect. When we arrived, she was waiting for us at the bus stop (just in front of the flat), she welcomed us, gave us a tour of the apartment and tips about where to go, what to see, the quickest way to get to the city centre/to the beach/to the supermarket/to the Holyrood park. We appreciated the fact that she helped us get started by having put some things in the kitchen : milk, eggs, bread, jam :)
The flat is perfectly located : 25min to get to Edinburgh centre, 10-15min to the Holyrood park, 5 min to the supermarket, 10min to Giovanni's Fish and Chips (pretty good cheap stuff there), 30min to Portobello beach : all of these, on foot ! We wanted to take time and decided to walk all the time but there are bus stops next to the apartment.
The apartment is spacious, there is Netflix on TV (which is pretty cool when you want to chill out after a long day walking in the city or after having walk to get to Arthur's Seat), there are two bathrooms, the bedroom is big and the bed is comfortable, there is everything you need to cook meals in the kitchen, every thing is clean, there are books and flyers about Edinburgh, a map on the wall, ...Well, it feels like home actually. I will definitely come back :)
