David's place was great, just as the photos suggest. It was clean, spacious and the bed was incredibly comfortable. I might even have to get the bed for myself. Even the sofa bed/air mattress combo was comfortable too. I didn't even know they made air mattress for pull-out couches, but it was great. We also decided to rent a car last-minute and parking wasn't difficult at all. We also took the metro a couple times. It's a pretty easy 10-minute walk to the metro.
Lastly, I can't emphasize enough how wonderful as hosts - we weren't around a lot so didn't get the chance to meet them. They were very responsive and helpful. I really enjoyed staying with them. We'll be back!
