We had a great stay in this apartment! The location was superb for seeing the city, with a 24hour Suma market across the street and plenty of bars and restaurants within a few minutes walk. The apartment itself was clean and maintained to a high standard. It's a beautiful space, the original tiled floors are still there and the high ceilings and cornices really make the apartment appealing. The beds were comfy, the water pressure in the showers was great and the amenities in the kitchen were excellent. They even had tea and coffee available.
The check in process was very easy - it's a keypad entry system, so all you need is the code. Our hosts were kind enough to give us a late check out as we had a very late flight home on the last day. We were extremely grateful to be able to leave our bags there during our last day!
The "no noise" policy after 10pm meant that the apartments were really quiet all night - a welcome relief from the bustling city. There's even a flashing light in the kitchen if you make too much noise after 10pm (which I activated by sneezing!!).
All in all, if you're looking for an awesome place to stay during your visit to Barcelona, I'd highly recommend this apartment. We will certainly be booking it again when we return!
