We spent 15 nights at this property during October 2017.
HOST: Alex was very friendly from the beginning. He was very flexible regarding check-in and check-out times...even letting us stay until 17:00/5:00pm on the check-out day. There is definitely room for improvement as far as responding to messages is concerned, but we always got the basics covered.
LOCATION: the neighborhood, which is full of locals and far from tourists, had tons of character. Although slightly rough around the edges, it felt perfectly safe. The metro stop on the street corner is a huge plus. There are plenty of interesting restaurants and bakeries within a few mins. walk. We can especially recommend the Sports Bar Italian Restaurant a few blocks away on Avinguda Diagonal =)
FLAT: The flat was generally very clean. It was very secure and offered a good level of privacy. The AC was very effective. The bed and couch were comfortable. The WiFi worked perfectly and the TV new enough to use a Chromcast. The kitchen is sufficient for couples during shorter stays or for people who don't cook much. However, it lacks supplies for longer stays. The bathroom is decently sized. During our stay the shower curtain was in desperate need of changing, as it had mildew and leaked, but this is easily remedied. Our main issue was that the flat had some air-quality issues that need addressing.
OVERALL, WE CAN RECOMMEND THIS LISTING =)
Ideally, it is best suited for couples on shorter stays, but it was sufficient during our longer stay. We plan on visiting Barcelona again in the next few years, and will definitely consider staying at Alex's place again.
