My boyfriend and I spent an entire month in this apartment.
It was clean and bright, as shown in the photos and very comfortable to live in. The bathroom is great - high pressure shower and completely refurbished.

When we had an issue with the Wifi and a leak from the bathroom upstairs, but Alex and his partners came to fix them both within 12 hours.

Just be aware that if, like me, you are a light sleeper you can expect to be woken up at night by the neighbourhood, but that is a trade-off for being in the center of Barcelona. Most central attractions are within walking distance and you're literally right next to the metro station. There are also some great places to eat nearby if you know where to look. Highly recommended!
