I didn’t get to meet Mabel, but her co-host Fabián was there and he is AMAZING!!!! The location can not be beat, you are literally walking distance from almost everything, and the train station is like a 4 minute walk from their home.
Fabián helped me figure out the transportation, and even arranged for a taxi to pick me up since I was leaving before the metro opened, and then walked with me to said taxi stop since I left at 5 in the morning.
The apartment is great, very clean, loved the art. Great water pressure.
I would definitely recommend them to anyone and will be staying again if I ever go back to Barcelona!
