Super friendly and helpful staff, attention to every detail.
The room was tidy but comfortable and well equipped (but no fridge & table was very small).
Cool and colorful furniture and design, local products offered (sweets, creams, etc) + anything that fits in you luggage (cups, pillows, ..) you can take it with you! If you pay, of course! ;-)
Finally, great location in the lively grassmarket, at the feet of the castle.
