We had a great time staying in Barcelona for a few days at Lluis's place. We are two parents and six kids and found the apartment size very reasonable for our needs. Our two youngest (age 5 and 7) slept on the pull out couch which is very comfortable though is obviously in a public area so for privacy needs I don't think my older ones would have been so happy to be sleeping there. The beds were really comfortable and LOTS of towels available and incredibly clean area. The toilets were clean and sanitized with that extra paper band across the seat to make us feel even better :)
the communication with Lluis is amazing. Answers with great details come quickly and conveniently! A booklet with maps and even coupons were waiting for us as well!
Check in was easy and smooth.
This apartment is in a great location being 7 minute walk to the bottom of La Ramblas. It is a little noisey at night in the room with the porch, but we were jet lagged having come from Canada so we likely would have been awake at 3 Am anyway ;)
The showers were clean and little soaps and shampoos were available for us. The water temperature is a bit finicky and changes every few minutes but this is not Lluis's fault as it is a building municiplaity issue.
Great location, incredibly clean, wonderful communicator! A++++++++
