We had a great time at Ursula's apartment.
The location in Leith is wonderful. You can reach a lot by foot - cafés, pubs, Tesco, a shopping centre. If you want to get to the centre and the Old Town, there is a bus stop right in front of the door - you don't even have to change buses.
The only small shortcoming was already known to us from other reviews. The apartment is very close to the mainstreet, which is very busy day and night. This didn't bother us as much, but if you have a very light sleep, it might be a thing.
All in all everything was fine and we would book Ursula's apartment again at any time.
