Pros:
Juan was an incredibly accommodating and helpful host. His communication was fast and upon arrival he gave us a map and an orientation of the apartment and then sat down with us for over an hour briefing us on all the sights to see in Barcelona along with the restaurants that are local favorites. The bedroom and apartment are large, clean and comfortable. Bedroom can be a little noisy if you are a light sleeper as it is overlooking the street but nothing some earplugs can't fix. Bed was VERY comfortable even for two people. Juan also made every effort to make sure we were comfortable by adjusting the thermostat to our desired temperature.
Juan made our trip very enjoyable and was extremely professional, giving us our space. We wouldn't have been able to enjoy our time the same way without his tips.
Cons:
Bed sheets and towels smelled musty as there was no dryer available. They were clean however but the smell was strong to which Juan apologized profusely and made every effort to try and remedy the situation.
Juan definitely deserves 5 stars and his place is a definite must-stay in Barcelona.
