This is a very attractive listing with the small terrace the main benefit. Ines, one of the staff was very responsive and helpful, but this is run as a business rather than classic airbnb style . We found the flat gloomy with idiosyncratic wiring and on the first day, we (and Ines who returned to help us) could only open the bolt to the terrace with great difficulty.
That said, you are in the centre of things here, and once you get onto the terrace, it is a little sanctuary from the noise and bustle beyond.
The pricing structure on the front page is a bit misleading. On the day we booked it was £42 but the final total with cleaning and service was well over £100 a night. More transparency needed on front page AirbnB (but hope the cleaners get the clearning fee).
