We had a lovely time staying at Nuria's flat. The location was very convenient for us - only one metro ride to Caja Magica for the tennis tournament. The neighbourhood feels local and trendy, with many hip restaurants around. We loved the restaurants Nuria recommended, especially Circo; great food and drinks for less than €20 per person.
The flat is very spacious for the three of us (could fit another one or two!). It's clean and bright, has TV and wifi. We didn't cook (why would you when there are so many restaurants around!), but there are a couple of supermarkets/grocers.
We'd definitely recommend Nuria's flat :-)
