We never met the host but communication was smooth and check in easy. It's a little weird because you have to walk up the main street to a restaurant to pick up the keys from someone that isn't the person you communicate with; but it was easy enough to find. The location is great for walking to or near Las Ramblas, the Gotic quarter, basically everything. We walked everywhere. Parking is very expensive and difficult so I don't recommend a car for this place. The apartment was clean, the furniture adequate, the kitchen great. The only minor downsides are that it is located in an alley off an awesome pedestrian street but it's where a lot of people leave garbage and the truck picks up in the middle of the night; and the shower is really not up to the same nice quality as the rest of the flat.
