David is a very nice host and although he wasn't at the house when I was there, he sent me very detailed messages with everything I could possibly need to know and made everything very easy to me.
The room was spacious and clean.
It was easy to get to the city-centre. There is the bus - very close - and the metro - 10/15 min away - or you can even walk to the White House if you're willing to walk (it's one hour away).
I would definitely stay at David's again.
