As everyone else has said, the great thing about this apartment is it's location - everything is on your doorstep. The apartment itself is high up and double-glazed which means it is reasonably quiet (although you can hear groups going past at night).
We loved the stylish decor and the beds were comfy which crisp white linen and fluffy towels. The bathrooms look like they had been recently refurbished so were sparkling. There's a great shower, but note only one for the apartment (the ensuite has a bath).
I'm not sure how typical this is but we had to pick up, and drop off, the keys from an Air B&B Buddy office about a 15min walk away, which is a pain when you have your bags with you. We did not realise this when we booked.
All-in-all we had a great stay at Tessa's and would recommend to other's wanting to stay centrally.
