We had a great stay at Mark's apartment! The location is perfect for exploring Princes Street/Calton Hill, and was round the corner from a wedding we attended at the Glasshouse.
The interior of the apartment is gorgeous, with the living room letting in lots of natural light. We liked the fact Mark's place had 2 bathrooms- both modern and clean.
Glenda (Mark's mum who manages check-in etc.) was quick to respond to our queries and very helpful!
We would definitely stay here again when visiting Edinburgh.
