In summary: Fortress on the outside and palace on the inside.
In detail: My family of four stayed 6 nights at Jordi's house. It was excellent.
The house was exactly as described on Airbnb and we couldn't be happier with our stay.
We wanted something comfortable, well appointed and a little away from the hustle and bustle of the main Barcelona tourist sites. Jordi's house provided all of those things.
The house was well fitted out, well presented and very clean. All of the beds were very comfortable and both showers were hot and had plenty of water pressure.
There was a separate air conditioning unit for each floor and they kept the house beautifully cool during the warm weather we have had this week.
The kitchen was well fitted out - including a microwave and coffee machine with pods. We did cook a couple of times and found that we had everything we needed.
We also made good use of the rooftop area with table and chairs and had drinks and meals up there.
The included internet ran at a good pace and met all of my family's needs.
We felt very safe in the area where Jordi's house is. The area is very quiet after the tourists from Park Guell leave for the day and the house is well secured from the outside and has an intercom system with camera to check out any guests before they enter.
My wife and sons and I all enjoyed our time at Jordi's house. I highly recommend it as a place to stay.
