I stay at Si's place before running the London Marathon as it was less than a 15 minute walk to the start line! It was a great base for chilling out and getting to the Expo at the Royal Docks too.
The place was nice and clean when we arrived and Si had left me a bottle of sparkling wine and a note to say good luck for the marathon which was a lovely touch. It's a great one bedroom apartment, that feels a lot larger because it's spread out well with lots of different rooms.
We had great communication with Si throughout, checking we got in okay and if there was anything else we needed before, during and after.
Would definitely recommend staying here!
