Excellent communication and very detailed directions, especially as our sat-nav seemed unable to cope with central Exeter, thank you! It is a very convenient place to park, 5 - 10 minutes walk from the centre although it is fairly steeply uphill.
The entrance is tricky, you'll need to block part of the road when you pull up to enter the key code. Our car is 4.3m long and 1.8m wide and it felt tight although it could have been a bit longer and still fitted (maybe 4.5 or 4.6m).
Overall, we'd highly recommend this space.
