I had a great stay at Lorena's apartment. It's in a charming old building and Lorena has put a lot of effort into making it stylish and comfy at the same time. Both the room and the rest of the apartment were very clean. I was staying in the room facing the inner courtyard. It doesn't get that much light but it's not like a travelled to Barcelona to stay inside. The good thing is that it is facing away from the street so you don't get any noise from traffic or construction outside :)
The location of the apartment is awesome as you are able to walk a lot of places within a relatively short time (e.g. 15 minutes to Placa Catalunya, 35 minutes to Sagrada Familia, 15 minutes to the beach, a park just 2 streets away..). The neighborhood has a lot of nice bars, restaurants and stores. I can only recommend Cafe del Born (for breakfast), La Paradeta (go for lunch) and Bormuth (great tapas) - all on the same block as the apartment.
Lorena is very welcoming and makes sure you have everything you need while giving you space. When I checked in, she did not only hand me over the keys but also a map of the city and a list of recommendations in the neighborhood. She was very busy with work but when we were both in the apartment, she was great to talk to and made me feel like I visited a friend instead of someone I had met only then. If I'm in Barcelona again, I'll make sure to stay with Lorena again.
