We really enjoyed our stay with Karen's mum, Alejandra. The room was as described, and the bed was very comfortable. We received a great welcome from Alejandra, and although we don't speak much Spanish we really enjoyed speaking to her as she is such a kind and bubbly person - we will go back next time with (hopefully) a better level of Spanish so that we can spend more time chatting to her. The apartment is very clean and had everything we needed, we were also pleased we could use the kitchen and living room. We did get lost on arrival as we made an error regarding which metro station was closest, but it's a short walk from Sant Ildefons station (line 5). We appreciated Alejandra's advice regarding places to visit, and she also provided us with numerous leaflets which were much appreciated. After our stay we headed to the airport, but if you're doing the same thing we would recommend you avoid buying the 'metro + airport' tickets advertised in the metro station as we changed at Sants Estacio and were denied access to the airport line as it is run by a different company, and had to pay for different tickets. The airport is not far from Alejandra's place, but probably easier and quicker to take a taxi. Coming back to the flat itself, we were very pleased with our choice and hope to stay with Alejandra again the next time we visit Barcelona.
