We had a pleasant stay at Gareth's apartment.
At first we had some trouble checking-in by keybox but Gareth helped us very quickly by bringing the missing key.
The apartment had all we needed, the only thing we would have wished for would be better wifi. The wifi often disconnected or was not found, what was a bit of a bummer because our mobile data service doesn't include the UK.
But all in all, we had a very good time :).
