We stayed with Martin and Guadalupe for 4 nights/5 days last week. Booooy, they were awesome :-) My flight arrived shortly before midnight and as soon as I landed I received a message from Martin with helpful hints on how to get from the Airport. Over the course of our stay we truly felt at home; they both were very welcoming and we felt at ease right away. M & G know Barcelona quite well and saved no effort in providing advice (cusine, sightseeing, night life, general safety, etc.) The apartment is very well kept, spotless clean, and has pretty much all the amenities one would want. On top of all that, they are both very interesting to talk to :-) would definitely recommend staying here!
