The apartment and the service is exactly as advertised. It is a little smaller than it looks in the pictures, but very clean and comfortable for us (we were two people). A nice, upscale neighborhood, about a 20 minute walk to the old city (Barri Gotic), less than 10 minutes from high end shopping and eating, and a block from the subway. The street the apartment is on is busy and a bus route, so you get traffic noise day and night.
Karolina was great, like having a hotel concierge. She was on-site every day, gave us advice and helped out on little problems like how to use the washing machine.

We would recommend it if you want a place that is a little bit
away from the busy tourist area and is clean, comfortable, efficient, but not quaint.
