I can't tell one thing which was not great in Sara's appartment during our 10 days stay there. Sara was very kind, helpful and responded to all our messages very quickly. The appartment was exactly what we were looking for: spacious, clean, in a safe and quiet area (planes are flying directly above the appartment though) very close to subway (this one has elevator, important when having a baby in a stroller :)) and a big shopping mall (El Corte Inglés). Would definitely recommend and hope to come back!
