Thomas was an excellent host - he greeted us when we first arrived and showed us everything we needed to know about the place. Additionally, he responded to our SMS's very quickly. The weather was cold but we could adjust the thermostat as needed and ended up making the place cozy warm.
We didn't encounter any problems at all.
Pro tips:
1. buy salad and frozen dinner from Trader Joe's (excellent prices!)
2. to get around, use the "Citymapper" app
