Leo made me feel very welcome from the beginning and was super nice. Communication was easy, Leo was quick to respond and alsways really helpful. The location of the flat is perfect: close to the Placa d'Espanya (access to the metro) and also only a 30 min walk from the Barrio Gotico. Lots of shops, supermarkets, bars, cafes and restaurants nearby, yet still very quiet at night. The room and the flat in general were very clean and had all the necessary appliances (fridge, microwave, coffee machine) were there. The shower was a bit sketchy (either too hot or to cold). Sadly, the room was a bit hot and didn't have any air condition, but Leo provided a fan, so it was ok in the end. :)
I definetely enjoyed my stay at Leo's place and would recommend it.
