Booking with Jordi & Jonathan proved to be a good choice. They're most welcoming hosts who do their best to assist you with any queries you might have. They took the initiative to message me before hand, just to make sure when I would arrive and if I needed any help finding their apartment (a timely 'Welcome to Barcelona' text message appeared as soon as I landed). Any message I sent them was promptly replied to.
Most importantly, their apartment is immaculate. I really appreciate cleanliness & tidyness and theirs is of hotel standard. Furthermore, everything in the kitchen, the shared bathroom, and the bedroom was in working order; it shows they take great care of the place they live.
The apartment itself is located a 2 minute walk from the L5 metro line, which has excellent connectivity to the city centre (with L4 & L1 lines one and two stops away, respectively).
Right across from their top floor apartment is a covered market where I bought good quality fruit, bread, cheese, olives, and fuet. There are also plenty of bistro's around of varying quality where I could get a nice croissant & coffee on my way down town. Although I must say, Jordi does quite a good coffee as well.
In conclusion, the stay at this host was good value for money and contributed to an excellent four days spent in Barcelona.
