We spent two weeks at Piedad's house in mid-April with our three kids, and we had a wonderful time. The house is perfectly situated, with all kinds of shops nearby, and only a 10 minute walk from the inner city. In the other direction, the Camí de Dalt de Sant Joan offers a great opportunity for a small half-day hiking activity. The location is also perfect if (like us) you're not travelling with a car. Both the main bus station and the airport are around the corner.
What else did we appreciate? The kitchen, which is equipped with most of the basic tools you'll need for cooking (a few more "advanced" things like a little hand blender might be handy, but no big deal!). The lovely outdoor area with its lemon, orange, and olive trees, and with a proper, large porch roof which is not only sun-, but also rainproof (very useful during that time of the year). Of course the place is very clean, maintained and decorated with great care by Piedad. And it has a lot of *space*. With its large living room, three bed- and three bathrooms, it never felt too small for the five of us. And we didn't even use the upstairs area much, which is an extra living+bedroom plus roof terrace.
When travelling during colder (and damper) times of the year, make sure to read the description carefully: it says there is no heating in the house -- which is no problem in summer and autumn, but in an April like the rainy one that we had, it can get a bit chilly and damp. We also found that the mattresses were a bit on the (very) "soft side", but that might just be due to our own taste.
In a nutshell: We would not hesitate to recommend it to others, and we would definitely come back here again ourselves!
