Montpelier is a really interesting neighbourhood, only 15 minutes walk from the main shopping area and 25 minutes walk to the waterfront. The street art is Instagram-able and there is something new to see at every turn.
There is on-street parking on the narrow street but you need to call Airbnb, book the parking permit at £5 per day and they will invoice you to make the payment. If you don't want to pay I understand there is free parking further away.
The house is comfortable with everything you need for a couple of days stay.
