The appartment is really comforatable, and modern, everything is clean and functions well, the bed is great and the kitchen has everything needed for a short stay of a week. My colleague who wast staying with me thoguht the same. I have been in the same building before and will come back to stay in one the two appartments that Marta rents out there. She welcomed me in person and was very helpful, arranging both earlier check in and later check out and taking care of my luggage for the rest of the day, which made my stay in Barcelona even more comfortable - i could go to the beach on my last day and have a shower and still enjoy the afternoon. The wifi works well, the aircon is easy to use, the area is residential but is close to some business-locations which suited me well, i could walk to the office in the morning. Sants Estacio is a short walk away if you want to go to Madrid for the day, as are two metro-stations. There are many nearby supermarkets, including one that is open Sundays (when i arrived) and lots of small, local restaurants with almost no tourists and very reasonable prices for good quality food. And the taxi ride to the airport is under 30 mins. I can only highly recommend the place!
